I can't for the life of me figure out how i'm supposed to sort multi-disk albums. For instance Pink Floyd's The Wall shows up in the playlist pane as:
bearcat@jaguarundi akradai % mutagen-inspect /home/hometheater/audio/pink_floyd/1979-the_wall/1-01-in_the_flesh\?.wv
-- /home/hometheater/audio/pink_floyd/1979-the_wall/1-01-in_the_flesh?.wv
- WavPack, 201.92 seconds, 44100 Hz (audio/x-wavpack)
