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

Here's a listahan of them:

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

Like I sinabi there is a longer listahan on that site but these are the only ones you can actually find on other albums.
