The Music Library

This database contains all information concerning music files that has been added to the Music Library. It is used in the Music portion of Kodi.

The current stable release of Kodi is using the following version of the database:

Kodi v20 - MyMusic82.db


Warning: The databases are critical components of Kodi. We strongly urge that you do not interfere with them, unless you have knowledge and experience with database designs.

Tables

album

An album. This equates to what Musicbrainz call a "release" and represents the unique release (i.e. issuing) of an item on a specific date with specific release information such as the country, label, etc. Hence album title and artist do not have to be unique as long as we have the release ID (Musicbrainz album ID), Kodi can handle different versions of the same album e.g. original release and then a later remaster (both same title and artist).

Notes

song

A song. It is the way that the individual track(s) from a music file are held in the music library. Generally a music file contains just one song, however it may contain more and have an associated cuesheet (separately or embedded) that identifies the individual tracks. A song may be from an album (the release of several tracks as one product so includes EPs etc. ), or a single. Singles from an artist (no album title given in the embedded tags) are internally linked with a fake album in the album table.

The music library can contain songs with the same title, artist credits, track number and album as long as they come from separate music files. Unexpectedly Musicbrainz Track ID is not unique on an album, recordings are sometimes repeated e.g. "[silence]" or on a disc set.
