Artist, Album, and Playlist Arts

If integrated Koel will attempt to fetch artists' images and album arts from Spotify, Last.fm, or MusicBrainz/Wikipedia whenever a song is played. You can upload custom images for artists, albums, and playlists via the corresponding edit form.

If there is no image available for an artist or album, Koel will use a default image (the Koel bird logo). For a playlist, a random "thumbnail stack" will be generated and used based on the tracks.

Newer versions of Koel also provide a command to fetch missing artist and album arts.
