Someone correct me if I'm wrong, but I don't see why you couldn't mount the drive on a linux box (or even possibly under Cygwin?) and use mp3tofid and rsync to copy your tunes over. I've never used mp3tofid or rsync for anything empeg related, so you'll have to do a quick search on them.

BTW, not to hijack the question, can someone tell me if you could mount the filesystem on a big-endian system, like a PowerPC Mac? Just to trying to satisfy my curiosity.
