* MusicBrainz
[[file:img/musicbrainz-logo.svg]]
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.
** MusicBrainz API
- Recording documentation: https://musicbrainz.org/doc/Recording
- Release documentation: https://musicbrainz.org/doc/Release
- Artist documentation: https://musicbrainz.org/doc/Artist
** searching & browsing
Search supports the full [[https://lucene.apache.org/core/7_7_2/queryparser/org/apache/lucene/queryparser/classic/package-summary.html#package.description][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…
#+BEGIN_SRC emacs-lisp
(musicbrainz-browse "release-group" "artist" "410c9baf-5469-44f6-9852-826524b80c61" "album|ep")
#+END_SRC
For slightly more legible output wrap with =musicbrainz-format=
#+BEGIN_SRC emacs-lisp
(musicbrainz-format
(musicbrainz-browse "release-group"
"artist"
"410c9baf-5469-44f6-9852-826524b80c61"
"album|ep"))
#+END_SRC
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
