I've been having trouble finding some of the songs that weren't on the main soundtrack for the movie. Some of the songs, like the Pixies' one at the end of the movie weren't on the official soundtrack!

I found a lijst of the other songs that weren't on the official soundtrack along with some albums link

Here's a lijst of them:

Svarga door Vas
Goin’ Out West door Tom Waits
No Love, No Nothin’ door Marlene Dietrich
Where is My Mind? door The Pixies

Like I zei there is a longer lijst on that site but these are the only ones u can actually find on other albums.
