I've never really bought soundtracks. I have Saturday Night Fever and The Wiz. I think the last one I bought was Mo Money in the early 90s. The good soundtracks were the ones pre-1980s like the Quincy Jones scores, those Gene Kelly style musical soundtracks, or blaxploitation. John Williams style orchestration is good to hear in a movie, but I wouldn't buy it or listen to it outside of the film. Something like Trouble Man or Batman, I just consider albums by Marvin Gaye and Prince, not soundtracks, per se.
