Favourite soundtrack?

What soundtracks do you guys find awesome? I know there's been a few threads like this, but it can be from anything. Games, films or TV.
I'll start off.
The soundtrack from the Pixar film Up is probably my favourite of all time.

Tron: Legacy's sound track is quite good (got it as a Christmas present, woo!), along with the ones for Super Meat Boy and VVVVVV. Civ 5's is alright, too.

I love the soundtrack of Up too.

My favourite is probably the soundtrack to Battlestar Galactica, Chicago or West Side Story. I can't decide between those three.
