OK, here is what comes to my mind right now:
Score for old Lucas arts Outlaws... Awesome spagethi western music.
Neverhood - terry s taylors awesome and crazy music with clay vibe :D
Braid - neat and colorful tracks for neat and colorful words
Atlantis 1,2 - had some absolutley gorgeous music, I listen to it to this day
Brutal legend - orgasm for every metalhead!
