If everyone could fix album statistics
If setlist.fm made it so that anyone could add or fix album information because there are a lot of songs that get list incorrectly or as other.
The list of albums comes from the database at MusicBrainz.org. To facilitate correct album assignments, make sure the songs are spelled/punctuated the same on Setlist.fm as they are at MusicBrainz. Also keep in mind that album assignments do not occur instantly, so if you add a new song to Setlist.fm, it could take some days/weeks before an album is assigned.
That being said, if you find album assignments that are missing or incorrect, you can report them in this thread and the Moderators will fix them.
