This is the essential Donnie Darko Soundtrack which has the score by Michael Andrews, some extra incidental music by Sam Bauer (the movie's editor) and his brother and roommate, as well as the "regular" songs by Echo & the Bunnymen, Tears for Fears, The Church, etc. are all on here.
All except one track: "Voices Carry" by 'Til Tuesday. It's the song that's playing in Donnie's bedroom when he's reading a book and his mom confronts him about not taking his medication.
Still worth five stars in my opinion.
