All IDs in Music­Brainz are UUIDs. For example: <code>95807106-af9f-417d-b1d0-d287c5504ec1</code>
Furthermore, Music­Brainz works with the Relatable TRM technology, which generates an acoustic fingerprint for a digital music file. This acoustic fingerprint is called the [[TRM|TRM ID]]. A user can run an MP3 (or other digital audio file) through a TRM ID generator like the MB Tagger, and then request the artist, album, and track information from [[MusicBrainz]]. With this retrieved information you can then rename the file and write clean ID3 tags. See [[MusicBrainz Tag|MusicBrainzTag]]<code><nowiki></nowiki></code>s for details.

MusicBrainz aims to be a comprehensive music database that will allow people and computers to have meaningful conversations about music. In order to facilitate these meaningful conversations, Music­Brainz needs to identify each artist, album, label and track with a unique identifier.

All IDs in Music­Brainz are UUIDs. For example: 95807106-af9f-417d-b1d0-d287c5504ec1

These IDs are also stored in tags in music files by the MusicBrainz Tagger applications. See MusicBrainz Tag for more detailed information.

Special Identifiers

There are some special identifiers used by MusicBrainz.

  • 89ad4ac3-39f7-470e-963a-56509c546377 is an artist ID used to represent various artists
  • 1c6c63fb-f9af-4669-92c5-a1594671766a is an artist ID used to represent an artist not in MusicBrainz database.

Other Identifiers used by MusicBrainz

  • Disc ID:
    • An ID calculated from the TOC of a CD.
  • PUID:
  • TRM:
    • These IDs were used for the old Relatable audio fingerprinting system. These IDs are no longer used.
