I'm having similar issues the last few months....not sure when it started. Under some circumstances it crashes when you try to play from within the playlist. Can make it tough to listen to the song to song flow or compare real relative volumes. Can easily work around ny printing a disk image and listening to that, but its annoying. I'm sure because its PPC it will never be fixed.
What I like to point out is that a sucky band in a great studio will produce a pristine recording of crap.
