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 lista of the other songs that weren't on the official soundtrack along with some albums link

Here's a lista of them:

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

Like I dicho there is a longer lista on that site but these are the only ones tu can actually find on other albums.
