Although {{kodi}} ignores the folder structure and the names of the folders and files, the structure of your folders is important as it affects the operation of other functions such as Import/Export, nfo files and Artwork. For example, if you have all your music files in one folder (which is possible), then you lose the ability to use local nfo files, local artwork, and the import/export module will not function correctly.

For this reason, {{kodi}} recommends the use of the following structure.

The following is {{kodi}} '''best practice'''. Remember use a layout that is nice for you, but '''tag accurately.'''

Remember that {{kodi}} does not extract any information from the filename. The only purpose the file name serves is to provide {{kodi}} a unique id to locate the file.
+
Song files require suitable tagging for use in {{kodi}}. While {{kodi}} can scan minimal tags into the library, it can lead to errors in the library and subsequent scraping. We recommend music files are tagged with MusicBrainz as detailed below.
  
The name you use for your files is your choice, but it is important that they are:
+
Remember that {{kodi}} does not extract any information from the filename, so the filename is your choice.
#Consistent
 
#Make sense
 
  
Example file names:
 
  
*Using the simple Song Name only = ''Everybody Wants to Rule the World.flac'' <br />
 
*Using a more complex combination of Artist-Album-Song  = ''Madonna-True Blue-Open Your Heart.flac''
 
 
If you would like to use track numbers in the file name, then ensure you include the disc number, even if there is only one disc. eg
 
*''0102 Everybody Wants to Rule the World.flac'' or ''D01T02 Everybody Wants to Rule the World.flac''
 
*''Madonna-True Blue-0106 Open Your Heart.flac'' or ''Madonna-True Blue-D01T06 Open Your Heart.flac''
 
 
Where 0102 = Disc 01 and Track 02

== Folders ==
 +
{{kodi}} is quite flexible with the folder structure. The diagram below is an '''example'''. You should group your albums in a manner that makes sense to you.
  
 +
To ensure {{kodi}} and other add-on processes can function efficently and correctly, the following is recommended.
 +
*Songs from the same album should be in the one folder
 +
*If there is more than one disk in the release, each disk should be in a sub-folder containing the songs from that disk
  
== Folders ==
 
Folders are used as follows:
 
#Album folders - Used to group '''songs''' from the same album into one folder
 
#Artist folders- Used to group '''albums''' from the same artist into one folder
 
#Source folder- Used to group '''Collections''' into one folder. (see next section)
 
  
The following is a typical recommended structure:

A source folder contains your media collection- in this case Music. This folder is then set as a Source in {{kodi}} which enables {{kodi}} to access your Music. (remember, Kodi does not know where your media is until you tell it)
+

In the Video section of Kodi, you would set one, or more, sources for Movies, TV Shows, Music Videos, Home Movies etc. The Music section oparates along the same principle.
 
 
 
As an example, you would save your music folders into separate Sources for the following:
 
*'''Single Artist type Albums '''
 
**These are albums released by a single artist or band
 
**This source will contain the Artist / Album / Song structure
 
**Examples- Kate Bush, Kylie Minogue, Tears for Fears etc
 
*'''Various Artists or Compilation Albums'''
 
**These are albums that contain songs from many different artists or bands.
 
**As there is multiple artists, there is no Artist folder. This source would contain the Album / Song structure.
 
**Examples- 2017 Grammy Nominees, So Fresh: Hits of 2016, Open Space: The Classic Chillout Album etc
 
*'''Classical Music'''
 
**Albums released by a single Composer. It is a separation from the main stream music in the Single Artist Source, which aids in better sorting in Kodi
 
**This source would contain the Artist / Album / Song structure, assuming single composer type albums, and groups all classical music in one source
 
**Examples- Vaughan Williams, Rachmaninov, Mozart etc
 
  
The idea is to group similar types of albums. This is not a requirement, and Kodi will still function if you grouped your music into a single source. It is a best practice guide which overcomes some hurdles with local files for compilation and collaboration type albums. These hurdles will no longer be an issue from v18 onwards.

In the diagram from the previous section ''Artist Music, Compilations, Classical'' and ''Audiobooks'' are Sources.

= Tagging =
Ever wonder how your music player always knows the name of the song, album, artist and track number of the music you play? This information comes from metadata embedded in the music file. If you purchased your music from an online store, then that store would have embedded the metadata in the file. If you ripped your own music, then the ripping software would have embedded the data into the file, probably without you even knowing. It is not uncommon that only minimal metadata is embedded, but this works very well on simple music players and is a  convenient solution to sorting your library on these players.
+
Most music files purchased or ripped by your favourite software have only minimal metadata embedded. Normally this is not a problem and works very well on simple music players.
 
<br /><br />
 
<br /><br />
{{kodi}} also makes use of this embedded metadata. {{kodi}}, being an advanced and feature rich player, requires a greater precision in the embedded tags. Any slight variance in, for example, the Album name between the tracks from the same album will see multiple entries in the library for that Album. Same with Artists. It is not uncommon to have a single album split into three similarly named albums. It is for this reason that there is a separation of the Scanning and Scraping processes for Music. The initial scan allows you to find and correct errors in tagging, before scraping. Failing to do that will create an unmanageable library.

The easiest method to comprehensively tag your music files is with MusicBrainz Picard.
 
  
 
As {{kodi}} scans your music collection, it copies the data contained in those tags into the {{kodi}} music database. The benefits of this are:

'''MusicBrainz Picard''' is the music file tagger software that can access the MusicBrainz database to locate metadata to embed into your music files. MBIDs are useful because names are not unique. The bigger and more diverse your music collection is, the more likely you will encounter Artists with the same name.
  
'''MusicBrainz''' is an open source music encyclopedia that collects music metadata and makes it available to the public. MusicBrainz has a database that, as of Sept 2017, [https://musicbrainz.org/statistics consists of over 1,258,860 Artists, over 1,866,600 albums and over 17,846,800 recordings].  
+
The advantages of tagging with MusicBrainz are:
 +
*They allow you to have different artists with the same name in your library e.g. "John Williams" the classical guitarist and "John Williams" the film music composer and conductor.
 +
*They negate inconsistencies in artist naming e.g. having "Peter Tchaikovsky" on some albums and "Piotr Czajkowski" on others
 +
*They allow you to have more than one release of an album in your library e.g. the normal and deluxe editions of an album
 +
*They clearly identify the artist and album in ways that names alone can not. This can then be used to accurately scrape additional artist and album information and locate the correct artwork
 +
*They allow the scraping process to be more efficient, otherwise an extra call is made to try and get an mbid first to use at the scraping sites, and each request from Musicbrainz must be throttled to 1 per sec which will slow the scraping process.
  
'''MusicBrainz Picard''' is the music file tagger software that can access the MusicBrainz database to locate metadata to embed into your music files. It is recommended that your music collection is correctly tagged using the tagging software [https://picard.musicbrainz.org/ MusicBrainz Picard]. This is a free download. There are other Taggers that are able to access the MusicBraniz database, but Picard seems to be friendliest to use.

Although {{kodi}} will populate the library with those minimal tags, the errors in those tags would create havoc in the library.

Although Picard is very easy to use, you must avoid blindly accepting everything offered by the software. It is important that you confirm the correct album was located. Due to the global nature of the database, there are many releases for a single album. These releases differ between countries, usually due to copyright requirements. This may lead you to inadvertendly select the incorrect release for your album, even though it is named exactly the same. The differences between releases may be as simple as different song ordering or the inclusion of additional bonus tracks.
  
Further information and guides can be found at the [https://picard.musicbrainz.org/ MusicBrainz Picard] site.
+
For the best tagging experience set the correct options in Picard, particularly the "Clear Existing Tags" option in settings. This option means that any old tags that may cause issues are wiped, preserving only the musicbrainz tagging. It will also be wise to tag using ID3v2.4 compatibility.

Once the music files are tagged, avoid modifying the MusicBrainz tags unless you clearly understand the relationship of the MBID's and the other related tags. For example, embedding MBID tags, but then editing the Artist tag or Album Artist tag will result in incorrect entries in the library.
 +
 
 +
For example:
 +
*If you need to change the artist or album artist tag you also have to edit the matching artist mbid tag and album artist mbid tag.
 +
*If Kodi finds a release mbid it will expect the artist mbid tags to also be present.

1 Introduction

This page provides the following information:

  • How the Music section differs from the Video section of Kodi
  • The recommended method to organise your music files
  • The recommended method for tagging your music files
  • Explanation of some commonly misunderstood Music File Tags
  • The Audio Files and Tags that Kodi reads and uses


2 Understanding the Music Library

There is a fundamental differences between video library operation and the music library operation:

  • The video library is based on using the filenames or folder names to obtain online data. If they are incorrectly named, then there are no scraper results and there will be no library entry.
  • The music library is based on scanning tags embedded in the music files. It ignores the folder names and structure and file names. Proper tagging is essential to ensure the library is populated correctly. Having slight variations in the tags for artist and album names could mean duplicated and unwanted entries.


3 Folder and File Structure

Although Kodi ignores the folder structure and the names of the folders and files, the structure of your folders is important as it affects the operation of other functions such as Import/Export, nfo files and Artwork. For example, if you have all your music files in one folder (which is possible), then you lose the ability to use local nfo files, local artwork, and the import/export module will not function correctly.

The following is Kodi best practice. Remember use a layout that is nice for you, but tag accurately.


3.1 Files

Song files require suitable tagging for use in Kodi. While Kodi can scan minimal tags into the library, it can lead to errors in the library and subsequent scraping. We recommend music files are tagged with MusicBrainz as detailed below.

Remember that Kodi does not extract any information from the filename, so the filename is your choice.


3.2 Folders

Kodi is quite flexible with the folder structure. The diagram below is an example. You should group your albums in a manner that makes sense to you.

To ensure Kodi and other add-on processes can function efficently and correctly, the following is recommended.

  • Songs from the same album should be in the one folder
  • If there is more than one disk in the release, each disk should be in a sub-folder containing the songs from that disk


The following is a typical folder structure:

f:\   ....................................(root)
 |__Artist Information  ..................(Artist Information Folder)
 |
 |__Artist Music   .......................(source folder)
 |  |__ Madonna   ........................(artist folder)
 |  |   |__ Beautiful Stranger (1999)   ..(album folder)
 |  |   |   |__ Song 1
 |  |   |   |__ Song 2
 |  |   |   |__ Song 3 etc
 |  |   |__ Bedtime Stories (1994)   .....(album folder)
 |  |   |   |__ Song 1
 |  |   |   |__ Song 2

3.3 Sources

A source folder contains your media collection- in this case Music. This folder is then set as a Source in Kodi which enables Kodi to access your Music.

In the diagram from the previous section Artist Music, Compilations, Classical and Audiobooks are Sources.

Setting and Scanning of Sources is covered in detail in the next step of the guide.


4 Tagging

Most music files purchased or ripped by your favourite software have only minimal metadata embedded. Normally this is not a problem and works very well on simple music players.

Kodi, being an advanced and feature rich player, requires greater accuracy with the embedded tags. Any slight variance in, for example, the Album name between the tracks from the same album will see multiple entries in the library for that Album. It is not uncommon to have a single album split into three similarly named albums. Also true for Artists. It is for this reason that there is a separation of the Scanning and Scraping processes for Music. The initial scan allows you to find and correct errors in tagging, before scraping.

This table has examples of errors in tagging, which will cause duplicated entries in the library...

Similar Name 1 Similar Name 2 Note
György Ligeti Gyorgy Ligeti Accented and unaccented names will create duplicate entries
The Best of The Very Best Of Inconsistent naming between songs of the same album and/or artist will cause duplicated entries
Madonna Madonnna Spelling mistakes will cause duplicated entries for albums and/or artists
Sting Sting and The Police Seen as two separate and unrelated Artists

As Kodi scans your music collection, it copies the data contained in those tags into the Kodi music database. The benefits of this are:

  • Once the scan is complete, the tags are not accessed again
  • All information is now obtained from the database. This has the benefit of dramatically increasing efficency and speed when navigating the library.
  • Now that a database entry exists, you are able to scrape additional information from online sources. This is covered later in the guide.


4.1 MusicBrainz

Kodi has strong support for MusicBrainz tagging. It is highly recommended that users tag their music files using MusicBrainz Picard.

MusicBrainz Picard is the music file tagger software that can access the MusicBrainz database to locate metadata to embed into your music files. MBIDs are useful because names are not unique. The bigger and more diverse your music collection is, the more likely you will encounter Artists with the same name.

The advantages of tagging with MusicBrainz are:

  • They allow you to have different artists with the same name in your library e.g. "John Williams" the classical guitarist and "John Williams" the film music composer and conductor.
  • They negate inconsistencies in artist naming e.g. having "Peter Tchaikovsky" on some albums and "Piotr Czajkowski" on others
  • They allow you to have more than one release of an album in your library e.g. the normal and deluxe editions of an album
  • They clearly identify the artist and album in ways that names alone can not. This can then be used to accurately scrape additional artist and album information and locate the correct artwork
  • They allow the scraping process to be more efficient, otherwise an extra call is made to try and get an mbid first to use at the scraping sites, and each request from Musicbrainz must be throttled to 1 per sec which will slow the scraping process.


Below is a screenshot of the main screen of the Picard software. A brief description of the layout as follows.

  • Top Left Box- Folder listing of your music collection
  • Top Centre Box- Albums are dragged and dropped here in preparation for matching and tagging. Pressing Lookup (greyed out) will commence the lookup process
  • Top Right Box- Matching albums are displayed here and your songs are overlayed. In the screenshot, songs 01, 08 and 09 have been matched to the suggested album. If all songs match and you agree the correct album was located, simply pressing Save will tag the album with the tags displayed in the Bottom Tag Box.
  • Bottom Tag Box - Selecting a song from the Top Right Box will display all available tag fields (left column), the current tags in the music file (Original Value column) and the MusicBrainz tags to be embedded in the music file (right column).

The example in the image below shows the following:

  • Most tags are missing (original value column)
  • The top three yellow entries are incorrect (original value column) and the corrections are in the right column
  • The green entries in the right column indicate new tags to be embedded
  • The black entries at the bottom of the list indicate no change to the existing tags as they are correct or not used by MusicBrainz.



Although Picard is very easy to use, you must avoid blindly accepting everything offered by the software. It is important that you confirm the correct album was located. Due to the global nature of the database, there are many releases for a single album. These releases differ between countries, usually due to copyright requirements. This may lead you to inadvertendly select the incorrect release for your album, even though it is named exactly the same. The differences between releases may be as simple as different song ordering or the inclusion of additional bonus tracks.

For the best tagging experience set the correct options in Picard, particularly the "Clear Existing Tags" option in settings. This option means that any old tags that may cause issues are wiped, preserving only the musicbrainz tagging. It will also be wise to tag using ID3v2.4 compatibility.


4.2 albumartists

Kodi requires the albumartists tag to correctly handle multiple album artists on the same album. This tag is not a default tag in MusicBrainz Picard and other tagging software. [1]

To include this tag add a new script under Options > Options > Scripting > Add new script and include the following code...

$setmulti(albumartists,%_albumartists%)


Once the music files are tagged, avoid modifying the MusicBrainz tags unless you clearly understand the relationship of the MBID's and the other related tags. For example, embedding MBID tags, but then editing the Artist tag or Album Artist tag will result in incorrect entries in the library.

For example:

  • If you need to change the artist or album artist tag you also have to edit the matching artist mbid tag and album artist mbid tag.
  • If Kodi finds a release mbid it will expect the artist mbid tags to also be present.

5 Ripping CD's

Kodi has integrated Audio-CD (CDDA) ripping functionality. In order to use this feature, first configure the CD ripping settings (to set which encoder quality to use and where to store the files). To Rip the entire CD, highlight the Audio CD from the My Music root listing and choose Rip Audio CD from the context menu. To rip a single track, enter the Audio CD, highlight the desired track, and choose Rip Audio Track from the context menu.

There is no requirement to use the Kodi CD Ripper. If you are comfortable using other ripping software, then we recommend you continue using that software.


6 Cue Sheets

Cue Sheets are used to provide index and playlist information for a large audio file. They are generally used in conjunction with either extracting from, or burning to, Music AudioCD. Cue sheets have the file extension ".cue", and are simple plain text files.

Kodi does provide basic support for using cue sheets to define individual tracks when an entire CD has been ripped into a single music file. However the information provided by the cue sheet standard is much more limited than that of standard tagging, hence to enjoy the full music library features it is recommended that tracks are ripped into separate files and fully tagged.
If you do not use Cue Sheets you can safely move onto the next step.


7 Streams

Various internet video and audio streams can be played back in Kodi as if they were locally stored on your media center by using STRM files. As long as the format and streaming-method (network-protocol) is supported by Kodi, stream can be added. These are basic text files that look like <name>.strm and contain a URL to the internet stream. STRM files can also be added to the video library and can have cover art, summaries, etc.

Some internet sites may have an add-on available that can also access these media streams, rather than having to manually create STRM files. See Add-ons for more information on how to find and install add-ons.


8 Technical Explanation: File tags

For many categories, such as genres and artists, Kodi supports multiple values in the one field. By default it uses the character sequence " / " to divide the entry into multiple values. This divider may be changed via advancedsettings.xml.


8.1 Resolving Compilations and Multiple Artists

Applies to v17 and below. v18 introduced the Artist information folder which solved these problems. You are encouraged to update to v18

Kodi reads the Album Artist tag in ID3, Ogg, APE and MP4 tags and uses it if available to assign an artist to the album (independently of the track's artist information). This is the "Album Artist" tag (in ID3 this is represented by the "TPE2" tag; in vorbiscomment (ogg) files "ALBUMARTIST", "ALBUM ARTIST" and "ENSEMBLE" are all supported). Multiple artists for either a track or album artist can be specified in "Artist1 / Artist2 / Artist3" format.

If no Album Artist tag exists, Kodi will use the first (primary) artist from the tracks as the Album Artist. Essentially we do a string comparison of all the track artists, and assign the common artists as the Album artist. This is generally the TPE1 tag in ID3.

As many users don't yet use the Album Artist tag, Kodi has an additional filter system for identifying compilation albums, where each track normally has a different artist. As Kodi scans a folder, it does the following:

  1. Identifies albums based on Album name alone in the folder and groups the songs that have the same Album name together as an album.
  2. Runs through each album's assigned songs. If there is 2 or more tracks with the same Track number, the group of songs must come from 2 or more albums, so the Album name is ruled out as a possible compilation.
  3. If any of the songs assigned to the Album name have an Album Artist tag, then Kodi assumes the user knows what they're doing, and this album is also ruled out from being a compilation.
  4. If two or more songs assigned to the Album name then have different primary artists, then the Album name is considered to be a group of songs from a compilation, and the Various Artists" tag is assigned as the album artist.
  5. Otherwise, if all the songs have the same primary artist but don't have the same full artist list (eg a song or two has an additional artist) then the album is assigned the primary artist as it's Album Artist, and we assume the additional artists are guest artists.


8.2 Ratings in ID3 tags

Ratings in ID3 tags are read via the POPM field, and (if this doesn't exist) in a custom (TXXX) field named "RATING". For the RATING field, we accept 1-5 as valid ratings. For the POPM field things are more complicated, as there is no established standard in place. We currently most closely respect what Mediamonkey does, and also have some support for what Windows Media Player 11 does. The POPM tag takes a value from 0..255, with 0 meaning no rating, 1 the worst, and 255 the best. We currently map these as follows:

POPM value Star rating
0
1 * This is a special case for Windows Media Player
2-8
9-49 *
50-113 **
114-167 ***
168-218 ****
219-255 *****


9 Audio Formats & Tags

9.1 Supported Audio Formats

Although the list of playable formats is quite comprehensive, it is not accurate to say that every Kodi installation will play every format. The ability to play some of the more obscure formats will depend upon the version of Kodi and the operating system in use. Some formats will require the installation of add-ons.


Default extensions for MUSIC:

.nsv .m4a .flac .aac .strm .pls .rm .rma .mpa .wav .wma .ogg .mp3 .mp2 .m3u .gdm .imf .m15 .sfx
.uni .ac3 .dts .aif .aiff .wpl .ape .mac .mpc .mp+ .mpp .shn .wv .dsp .xsp .xwav .waa .wvs .wam
.gcm .idsp .mpdsp .mss .spt .rsd .sap .cmc .cmr .dmc .mpt .mpd .rmt .tmc .tm8 .tm2 .oga .url
.pxml .tta .rss .wtv .mka .tak .opus .dff .dsf .m4b .cue .zip .rar

It is possible to add or remove extensions for Music, using the following XML tags. Useful if you keep, say, FLAC and mp3 versions of music in the same folder. The <remove> tag can be used to remove mp3 from being listed in the library, leaving only the higher quality FLAC being displayed.

<musicextensions>
  <add>.ex1|.ex2</add>
  <remove>.ex3|.ex4</remove>
</musicextensions>



9.2 Supported Metadata Containers

The following metadata containers are supported by Kodi

Metadata Container Note
APEv2 tag
ASF
Generic Tag A generic tag for basic data from other odd file types
ID3 v1, v2.3 and v2.4
MP4
Xiph.org Vorbis Comments


9.3 Common File & Tag Combination

You will notice that not all the tags listed in the section Supported Audio Formats above are listed in the following table. Those formats that are ommitted do not have provision to support embedded tags. If your collection contains any of these unsupported formats, you will be unable to scan the music into the library. Your options are:

  1. Convert your audio file to a supported format and tag using MusicBrainz Picard. (recommended)
  2. Access your music via the File Manager or via File View

Kodi supports the following common Audio File and Tag Formats

Metadata container Additional Filename extensions
APEv2 tag ape, mp3, aac, wv, mpc
ASF asf, wmv, wma
Generic Tag it, mod, module, nst, wow, s3m, xm
ID3 v1 mp3, aac
ID3 v2 mp3, aac, tta, aif, aiff, wav, flac
iTunes MP4 .3g2 .m4a .m4b .m4p .m4r .m4v .mp4
Xiph.org flac, oga, ogg, opus

Note:

  • FLAC files- xiph tags override id3v2 tags
  • mp3 files can have either id3 or APE tags
  • mka, dsf, dff - ID3v2 format read but are handled by ffmpeg tag reader and it does not support all tags from IDE standard)


9.4 Tags Kodi reads

Kodi will scan the following tags embedded in the music file. The column Kodi Version indicates the version of Kodi that the tag was introduced, and will work in subsequent versions.
