Here's my list....
Gladiator (love that Waltz timing)
Paris Texas (just awesome work from Ry Cooder)
Taxi Driver (that slow menacing beat)
Apocalyse Now. (a mate had a 4 record set of this, which included some of the dialogue along with the music in chronological order...been trying to find it ever since....)
Honourable mention to Little Stevie who supplied the guitar duel on Crossroads.
