What is the music that plays towards the tail end of the new X2 trailer?
 

I'm talking about the music that plays towards the end of the "roll call" trailer featured in showings of Daredevil. It sounds like something out of Conan The Barbarian but is no way part of that classic Basil Poledouris score. I can't get it out of my head and am dying to know where that music originally came from.

Just for clarification, I'm not reffering to the trailer(s) that features "Mars the Bringer of War" by Gustav Holst. I'm talking about the latest X2 trailer.

Is there maybe a site that keeps tabs of music used in trailers? I mean, there's a site for practically everything else.
