Soul Music, Collector's Edition
This was not my favorite disc world book. I let it sit unlistened to for long spans of time, though, which might have been the problem... I had trouble keeping track of what was going on. There were a lot of funny references to modern music culture (well, not recent stuff, but within the last 40 years or so, and I'm old enough to have caught most of it.) Whenever I read Pratchett, I'm struck by how ridiculously clever he is, and how un-clever I really am.
