My 2 faves:
Dead Man . Awesome film, awesome soundtrack (Neil Young)
Southern Comfort, in a similar vein – Ry Cooder. Awesome film too.
Donkey Punch has a damn good soundtrack. Great soundtrack, great film (actually, terrible film :D )
Morvern Caller (with Samantha Morton) is a bit miserable, but the music is fab (Can, Aphex Twin, Velvets.. etc)
Ocean’s Eleven prob already been mentioned.
The Hit from 1984 I have the soundtrack on vinyl somewhere. I thought it was flamenco, but this trailer has some dodgy riffing. I’ll have to dig it out and have a listen. https://www.imdb.com/title/tt0087414/?ref_=fn_al_tt_1
