Discogs Plugin#

The discogs plugin extends the autotagger's search capabilities to include matches from the Discogs database.

Files can be imported as albums or as singletons. Since Discogs matches are always based on Discogs releases, the album tag is written even to singletons. This enhances the importers results when reimporting as (full or partial) albums later on.

Genre Mapping#

Discogs uses styles for the more specific classifications and genres for the broader ones. The plugin therefore uses Discogs styles as the primary source for the beets genres field, because beets treats genres as the main multi-valued genre field.

The broader Discogs genres values are written to the beets style field. If append_style_genre is enabled, those broader Discogs genres values are also appended to beets genres.

For example, a Discogs release with styles set to ["Techno"] and genres set to ["Electronic"] becomes beets genres = ["Techno"] and style = "Electronic" by default. With append_style_genre enabled, beets genres becomes ["Techno", "Electronic"].

Installation#

To use the discogs plugin, first enable it in your configuration (see Using Plugins). Then, install beets with discogs extra

pip install "beets[discogs]"

You will also need to register for a Discogs account, and provide authentication credentials via a personal access token or an OAuth2 authorization.

Matches from Discogs will now show up during import alongside matches from MusicBrainz. The search terms sent to the Discogs API are based on the artist and album tags of your tracks. If those are empty no query will be issued.

If you have a Discogs ID for an album you want to tag, you can also enter it at the "enter Id" prompt in the importer.

OAuth Authorization#

The first time you run the import command after enabling the plugin, it will ask you to authorize with Discogs by visiting the site in a browser. Subsequent runs will not require re-authorization.

Authentication via Personal Access Token#

As an alternative to OAuth, you can get a token from Discogs and add it to your configuration. To get a personal access token (called a "user token" in the python3-discogs-client documentation):

login to Discogs;
visit the Developer settings page;
press the Generate new token button;
copy the generated token;

place it in your configuration in the discogs section as the user_token option:

discogs:
    user_token: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

Configuration#

This plugin can be configured like other metadata source plugins as described in Using Metadata Source Plugins.

Default#

discogs:
    apikey: REDACTED
    apisecret: REDACTED
    tokenfile: discogs_token.json
    user_token:
    index_tracks: no
    append_style_genre: no
    separator: ', '
    strip_disambiguation: yes
    featured_string: Feat.
    extra_tags: []
    anv:
        artist_credit: yes
        artist: no
        album_artist: no
    data_source_mismatch_penalty: 0.5
    search_limit: 5

index_tracks (default: no)#

Index tracks (see the Discogs guidelines) along with headers, mark divisions between distinct works on the same release or within works. When enabled, beets will incorporate the names of the divisions containing each track into the imported track's title.

For example, importing divisions album would result in track names like:

Messiah, Part I: No.1: Sinfony
Messiah, Part II: No.22: Chorus- Behold The Lamb Of God
Athalia, Act I, Scene I: Sinfonia

whereas with index_tracks disabled you'd get:

No.1: Sinfony
No.22: Chorus- Behold The Lamb Of God
Sinfonia

This option is useful when importing classical music.

append_style_genre (default: no)#: Appends the broader Discogs genres values to beets genres after the specific Discogs styles values already stored there. See the Genre Mapping section above for the default field mapping and an example.

separator (default: ", ")#: How to join multiple Discogs genres values when writing the beets style field.

Changed in version 2.7.0: This option now only applies to the style field as beets now only handles lists of genres.

strip_disambiguation (default: yes)#: Discogs uses strings like "(4)" to mark distinct artists and labels with the same name. If you'd like to use the Discogs disambiguation in your tags, you can disable this option.

featured_string (default: Feat.)#: Configure the string used for noting featured artists. Useful if you prefer Featuring or ft..

extra_tags (default: [])#

By default, beets will use only the artist and album to query Discogs. Additional tags to be queried can be supplied with the extra_tags setting.

This setting should improve the autotagger results if the metadata with the given tags match the metadata returned by Discogs.

Tags supported by this setting:

barcode
catalognum
country
label
media
year

Example:

discogs:
    extra_tags: [barcode, catalognum, country, label, media, year]

anv#

This configuration option is dedicated to handling Artist Name Variations (ANVs). Sometimes a release credits artists differently compared to the majority of their work. For example, "Basement Jaxx" may be credited as "Tha Jaxx" or "The Basement Jaxx". You can select any combination of these config options to control where beets writes and stores the variation credit. The default, shown below, writes variations to the artist_credit field.

discogs:
    anv:
       artist_credit: yes
       artist: no
       album_artist: no

Contributor credits#

When Discogs provides artist roles on a track, beets uses them to separate main artists from other credited contributors. Main artist fields such as artist, artists, artist_credit, artists_credit, artist_id, and artists_ids keep the primary artist credits, while featured artists from track roles are appended using featured_string.

Discogs contributor roles are also imported into beets' multi-value performer fields when available. This includes remixer, lyricist, composer, and arranger credits, which populate remixers, lyricists, composers, and arrangers respectively.

data_source_mismatch_penalty (default: 0.5)#

Penalty applied when the data source of a match candidate differs from the original source of your existing tracks. Any decimal number between 0.0 and 1.0

This setting controls how much to penalize matches from different metadata sources during import. The penalty is applied when beets detects that a match candidate comes from a different data source than what appears to be the original source of your music collection.

Example configurations:

# Prefer MusicBrainz over Discogs when sources don't match
plugins: musicbrainz discogs

musicbrainz:
    data_source_mismatch_penalty: 0.3  # Lower penalty = preferred
discogs:
    data_source_mismatch_penalty: 0.8  # Higher penalty = less preferred

# Do not penalise candidates from Discogs at all
plugins: musicbrainz discogs

musicbrainz:
    data_source_mismatch_penalty: 0.5
discogs:
    data_source_mismatch_penalty: 0.0

# Disable cross-source penalties entirely
plugins: musicbrainz discogs

musicbrainz:
    data_source_mismatch_penalty: 0.0
discogs:
    data_source_mismatch_penalty: 0.0

Tip

The last configuration is equivalent to setting:

match:
    distance_weights:
        data_source: 0.0  # Disable data source matching

source_weight (default: 0.5)#: Deprecated since version 2.5: Use data_source_mismatch_penalty instead.

search_limit (default: 5)#: Maximum number of search results to return.

Troubleshooting#

Several issues have been encountered with the Discogs API. If you have one, please start by searching for a similar issue on the repo.

Here are two things you can try:

Try deleting the token file (~/.config/beets/discogs_token.json by default) to force re-authorization.
Make sure that your system clock is accurate. The Discogs servers can reject your request if your clock is too out of sync.

Matching tracks by Discogs ID is not yet supported. The --group-albums option in album import mode provides an alternative to singleton mode for autotagging tracks that are not in album-related folders.
