MusicBrainz Identifiers

MusicBrainz Identifiers are URIs which contain a Universally Unique Identifier (UUID) in its 36 character ASCII representation. In situations where the context is clear (such as file tags), just the UUID part can be used, leaving a relative URI.

Types of MusicBrainz ID

  • ArtistID ( http://musicbrainz.org/artist/<UUID> )
  • ReleaseID ( http://musicbrainz.org/release/<UUID> )
  • TrackID ( http://musicbrainz.org/track/<UUID> )
  • DiscID ( http://musicbrainz.org/discid/<discid> )
  • TRM
  • PUID

Special UUIDs

There are a number of Universally Unique Identifiers that have a special meaning.
