In Muse's latest album the last song (Isolated System) plays a piano loop that I just know I've heard before, possibly in a film soundtrack. The loop is best heard in the first 10 seconds (edit: better yet, from 2:04-3:00). I desperately want to find where I know it from, it's driving me mad. Any and all help is much appreciated!

(I thought it might be the Moon soundtrack, but it isn't)
