I can think of 3 offhand, and I don't really prefer one to the others.
My favorite soundtracks are from 'John Carpenter's Vampires' and Volume 1 & 2 from 'Dazed and Confused'.
I forgot what the soundtrack was like. As far as that goes, I can't remember what happens in the film either. I guess I'll have to dig for my video and re-watch it. LOL!
I'm probably gonne take some heat for this..but my favorite movie soundtrack is from Twilight. Even after almost 2 yrs...I still listen to the Twilight soundtrack every day. 'Spotlight' and 'I caught myself' are my favorite songs from it. I was hoping to love the New Moon soundtrack just as much but its just didnt have the same effect on me as Twilights..though 'Possiblities' and 'I believe' are really good.
