|
||||
|
||||
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.

** 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
|
||||
|
||||
#+BEGIN_SRC emacs-lisp
|
||||
(musicbrainz-search "recording" "taema")
|
||||
#+END_SRC

Autechre albums & eps
|
||||
|
||||
docs provide the example URL https://musicbrainz.org/ws/2/release-group?artist=410c9baf-5469-44f6-9852-826524b80c61&type=album|ep
|
||||
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-search-artist "Autechre")
|
||||
(musicbrainz-format (musicbrainz-browse "release-group" "artist" "410c9baf-5469-44f6-9852-826524b80c61" "album|ep"))
|
||||
#+END_SRC
|
||||
|
||||
#+RESULTS:
|
||||
| Autechre | 410c9baf-5469-44f6-9852-826524b80c61 |
|
||||
A more interactive approach could start with =(musicbrainz-search "artist" "Autechre")= or =(musicbrainz-search-artist "Autechre")= Which returns the MBID required for the lookup → =410c9baf-5469-44f6-9852-826524b80c61=
|
||||
|
||||
The MBID can be checked if needed, with =(musicbrainz-mbid-p "410c9baf-5469-44f6-9852-826524b80c61")=
|
||||
|
||||
The MBID can then be used for specific lookups…
