Allmusic.com has an interesting write-up on the Donnie Darko soundtrack, and listening to song samples on Amazon.com seems to show the U.S. disc to be primarily "new age" or "space" music with the final track being the standout "Mad World". There's an import CD of the soundtrack from the UK available beginning October 4, 2005, which has more musical variety, including tracks by The Church and others. It's pricey though, around $37, but it's a double CD.
