What's your favorite movie soundtrack?

[Wigwam]

i just saw Tuhmbsucker and thought the soundtrack was awesome, all of it was done by The Polyphonic Spree but it's not always as cheerful as the regular Spree, which is good.
Also there are several Elliott Smith tracks, 2 of which (i think) were unreleased until now.
By the way my favorite soundtrack would probably be Big Lebowski (because the songs just fit so damn perfectly) and Pulp Fiction for the same reason (only it doesnt sound as good apart from the film)
