MusicBrainz

MusicBrainz is a community-maintained open source encyclopedia of music information. The REST-based webservice API can be used for direct access to MusicBrainz data with output in XML and JSON.

This code provides a simple, incomplete yet possibly useful interface to some of the MusicBrainz and ListenBrainz APIs from emacs for exploratory use in org-mode or behind the scenes sending listening metadata.

searching & browsing

Search supports the full Lucene search syntax.

some examples

The API docs provide an example search for “Autechre albums & eps” using the URL https://musicbrainz.org/ws/2/release-group?artist=410c9baf-5469-44f6-9852-826524b80c61&type=album|ep

The equivalent function (which returns a raw response as an alist) would be…

(musicbrainz-browse "release-group" "artist" "410c9baf-5469-44f6-9852-826524b80c61" "album|ep")

For slightly more legible output wrap with musicbrainz-format

(musicbrainz-format
 (musicbrainz-browse "release-group"
                     "artist"
                     "410c9baf-5469-44f6-9852-826524b80c61"
                     "album|ep"))

A more interactive approach could start with (musicbrainz-search "artist" "Autechre") or (musicbrainz-search-artist "Autechre") Which returns an MBID required for the lookup 410c9baf-5469-44f6-9852-826524b80c61

The MBID can be used for specific lookups (and checked if needed using musicbrainz-mbid-p )

MBID

“One of MusicBrainz' aims is to be the universal lingua franca for music by providing a reliable and unambiguous form of music identification; this music identification is performed through the use of MusicBrainz Identifiers (MBIDs). An MBID is a 36 character Universally Unique Identifier that is permanently assigned to each entity in the database, i.e. artists, release groups, releases, recordings, works, labels, areas, places and URLs. MBIDs are also assigned to Tracks, though tracks do not share many other properties of entities.” https://musicbrainz.org/doc/MusicBrainz_Identifier

(musicbrainz-artist-to-mbid "Autechre")

returns 410c9baf-5469-44f6-9852-826524b80c61

(musicbrainz-mbid-p "410c9baf-5469-44f6-9852-826524b80c61")
