Clint Mansell Pi Soundtrack Access

Is this what you were thinking of?

You're likely thinking of the soundtrack for the film "Moon" (2009) or more probably "Pi" (1998), both of which feature music by Clint Mansell.

You're referring to the soundtrack for the 2006 film "Clint Mansell" doesn't seem right, I think you meant "Requiem for a Dream" doesn't seem right either... Ah, got it!
