AcousticBrainz Plugin#

The acousticbrainz plugin gets acoustic-analysis information from the AcousticBrainz project. This plugin is now deprecated since the AcousicBrainz project has been shut down.

As an alternative the beets-xtractor plugin can be used.

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


The AcousticBrainz project has shut down. To use this plugin you must set the base_url configuration option to a server offering the AcousticBrainz API.

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.


To configure the plugin, make a acousticbrainz: section in your configuration file. The available options are:

  • 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).

  • base_url: The base URL of the AcousticBrainz server. The plugin has no function if this option is not set. Default: None
