The Discogs section shows what Discogs releases your songs have been matched to. In the left hand side we group the matches by the first letter of the album artist, if the first letter is not a letter they are put into the * grouping. Expanding on one of the letter groupings lists the artists starting with that letter in alphabetical order. Selecting an artist from the list shows how your songs have been matched to their releases on the right hand side of the report. Songs can be matched to Discogs either by a direct search to Discogs or by a relationship existing from a MusicBrainz album to a Discogs release.
