AcousticBrainz Plugin
*********************

The "acousticbrainz" plugin gets acoustic-analysis information from
the AcousticBrainz project.

Enable the "acousticbrainz" plugin in your configuration (see Using
Plugins) and run it by typing:

   $ beet acousticbrainz [-f] [QUERY]

By default, the command will only look for AcousticBrainz data when
the tracks doesn't already have it; the "-f" or "--force" switch makes
it re-download data even when it already exists. If you specify a
query, only matching tracks will be processed; otherwise, the command
processes every track in your library.

For all tracks with a MusicBrainz recording ID, the plugin currently
sets these fields:

* "average_loudness"

* "bpm"

* "chords_changes_rate"

* "chords_key"

* "chords_number_rate"

* "chords_scale"

* "danceable"

* "gender"

* "genre_rosamerica"

* "initial_key" (This is a built-in beets field, which can also be
  provided by Key Finder Plugin.)

* "key_strength"

* "mood_acoustic"

* "mood_aggressive"

* "mood_electronic"

* "mood_happy"

* "mood_party"

* "mood_relaxed"

* "mood_sad"

* "moods_mirex"

* "rhythm"

* "timbre"

* "tonal"

* "voice_instrumental"


Automatic Tagging
=================

To automatically tag files using AcousticBrainz data during import,
just enable the "acousticbrainz" plugin (see Using Plugins). When
importing new files, beets will query the AcousticBrainz API using
MBID and set the appropriate metadata.


Configuration
=============

To configure the plugin, make a "acousticbrainz:" section in your
configuration file. There are three options:

* **auto**: Enable AcousticBrainz during "beet import". Default:
  "yes".

* **force**: Download AcousticBrainz data even for tracks that already
  have it. Default: "no".

* **tags**: Which tags from the list above to set on your files.
  Default: [] (all)
