Shows what changes have actually been made to your actual files including file renaming. The left hand side lists all modified folders as a file tree. Each leaf folder can be selected and then all the files that have been modified in that folder are listed on the right hand side together with details indicating if they have been matched to All Music Guide, MusicBrainz release, Discogs release, MusicBrainz song or Acoustid song only. If you select one of these files on the right hand side it expands to show all the fields that have been added,modified or deleted.
The song changes view is useful for drilling down to a particular file and seeing viewing what changes have been made for that song..
