Help me ID a song, please!

I cannot figure out where I originally heard the song that is playing in this video:
YouTube - Halo 3 Hayabusa Armor finished (I'm not referring to the very first song that plays when the video loads)

I heard this song several weeks ago and I don't remember if it was from a trailer I watched or from an mp3 I heard someone else playing. I've been wracking my brain trying to figure it out and I just can't find the original source. If you know it, please let me know

There's an error with that video there (at least for me, at this very moment). You tube puts up its error message on it when I try to play it "An error occurred, please try again later"... bummer.


---edit---

Ok, a few attempts later and it finally decided to work. The song does sound familiar, but I'm not sure from where

Well a friend of mine pointed it out....

In case yer wondering now, it is called Lux Aeterna
YouTube - Lux Aeterna By Clint Mansell

I had heard a version of it from the LotR Two Towers trailer that I recently watched for whatever reason. And it was on the soundtrack to the movie Requiem for a Dream.

Whew...glad that is over with. Having a song in your head and not knowing what it is is the worst......."Hmm hmm Himmmm".
