There is a "soundtrack" for Angst that was released back in 1984, but it only includes remixes of some of the songs from the film, so it's not even a real sountrack.

I wish the actual original sountrack would be released in some form; there were a lot of songs in the film that I liked, particularly the one that plays during the cafe scene, and the one that plays when he's driving in the car and looking at the photos.
