[TOMT] Song used in a Halo 3 promotional. More info in comments.

So there was this song in an alternative soundtrack for the trailer where the camera pans backwards and in the end Master Chief steps out of a dustcloud and looks over the huge Covenant crater.

I've tried searching all over Youtube but can't find it. Iiirc it was a slow roch ballad of some sort and cointained some line like this: "we live in free cities" or something similar.

Thanks a bunch!
