MusicBrainz is a community-maintained open source encyclopedia of [[https://musicbrainz.org/doc/About][music information]]. The REST-based [[https://musicbrainz.org/doc/MusicBrainz_API][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.

** 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.”
