I have all my tracks in folders like this:
...\artist\album\01-album.mp3
...\artist\album\02-album.mp3
...\artist\album\03-album.mp3
e.g.
...\Michael Connelly\Trunk Music\01 - Trunk Music
When I pack them, AlbumMaker correctly shows the album as "album", but the artist is either "various" or "01" (the number at the beginning of the first file).
I would expect it to be "artist". That could be guessed from the folder, and the ID3 tag for all the files says the same.
