2 Understanding the Music Library
It is important to understand the fundamental differences between video library operation and the music library operation:
- The video library is based on using the filenames to obtain online data. If the video files 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 structure and file names. Correct 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 that Kodi does not extract any information from the filename.
The name you use for your files is your choice, but it is important that they are:
- Make sense
Folders are used as follows:
- Artist information folder- used as a central repository containing metadata and artwork for all Artists in the library
- 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:
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 | | | |__ Song 3 etc | | |__ Like A Prayer (1989) .......(album folder) | | | |__ Song 1 | | | |__ Song 2 | | | |__ Song 3 etc | |__ Simply Red .....................(artist folder) | |__ Picture Book (1985) ........(album folder) | |__ Song 1 | |__ Song 2 | |__ Song 3 etc | |__Compilations .......................(Source) | |__ Essential Eighties .............(album folder) | | |__ Song 1 | | |__ Song 2 | | |__ Song 3 etc | |__ 100% Hits- Best of 2005 ........(album folder) | |__ Song 1 | |__ Song 2 | |__ Song 3 etc | |__Classical ..........................(Source) | |__Audiobooks ........................(Source)
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.
Most music files purchased or ripped by your favourite software has 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.
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. It is recommended that your music collection is correctly tagged using the tagging software MusicBrainz Picard. This is a free download.
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).
It is important to note that a lot of music is distributed with only the basic metadata embedded, as can be clearly seen in the screenshot below. (Original Value 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.
Kodi requires the albumartists tag to correctly handle multiple album artists on the same album. This tag is not a default tag in MusicBrains Picard and other tagging software. 
To include this tag add a new script under Options > Options > Scripting > Add new script and include the following code...
Once the music files are tagged, it is important to 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.

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.
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.
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:
- Identifies albums based on Album name alone in the folder and groups the songs that have the same Album name together as an album.
- 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.
- 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.
- 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.
- 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.
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|
|1||* This is a special case for Windows Media Player|
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 .cue .aif .aiff .wpl .xspf .ape .mac .mpc .mp+ .mpp .shn .zip .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 .dtshd
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
|Generic Tag||A generic tag for basic data from other odd file types|
|ID3||v1, v2.3 and v2.4|
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:
- Convert your audio file to a supported format and tag using MusicBrainz Picard. (recommended)
- 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|
- 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.
|Kodi Version||Vorbis (.Flac)||ID3v2 (.mp3)||APE||MP4||ASF|
