I guess you don't like books?  If I had a bunch of money for the itunes store, and if I thought the audio quality was totally unacceptable there, I would look either at digital books or maybe some audio books. 

Psycho - Bernard Hermann Days of Heaven - Ennio Morricone Band a Parte (Band of Outsiders) - Michel Legrand One from the Heart - Tom Waits The Shining (not really a soundtrack but great music by Bartok and Penderecki, and a good version of Dies Iraes by Wendy Carlos).
