You know, I had a roommate in college who had that soundtrack. I always found that concerto disconcerting, because none of the tracks on the score seemed to finish. I'd be interested to hear that completed concerto to see if I still find it as unsettling.Oh, and Michael Nyman's Piano Concerto, which was assembled out of his music for The Piano.
I own quite a few scores, but I don't listen to them very much. A few that I really enjoy when I do listen to them:
Unbreakable
Gettysburg
Medicine Man
Tea with Mussolini
The Time Machine
Star Trek 2009
Star Trek Insurrection
Star Wars Attack of the Clones
