Shows what MusicBrainz songs your songs have been matched to. Sometimes it is not possible to identify a release that a group of songs can be matched to but it is possible to identify the names of the individual songs (know as recordings in MusicBrainz terminology). In the left hand side we group the matches by the first letter of the track 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 MusicBrainz songs on the right hand side of the report.
