This is such an astounding soundtrack, I remember hearing this album a long time ago and not really liking it (but I was young), then watching the movie and thinking, I've heard this music before...WHERE HAVE I HEARD THIS!? Google solved that problem. Just soo good though.
I think it's actually a little underrated. People were expecting an album and wrote it off when it didn't meet their expectations; as a soundtrack, it's way above par.
