Well, as long as the thread is still bumped, I guess I may as well post what I've (surprisingly quickly) found since my last post.
I'm also fairly certain that one of the Gamelan samples from "PowerFX: New World Order 2" was used in "Nitro Mantra" from "Ridge Racer 6", but I can't figure out which, it's so subtle, and it's probably only partial use of one sample.
