It's excellent theme music, dark and majestic, and with a good beat to it, and I like near the end there is even hints of techno/electronic music going on. Atmospheric music can do a lot for the game, for example, who can forget the great and epic fantasy theme music to Elder Scrolls Oblivion, and Fallout 3 also had a good theme too. I think one of my all time favorites (not just the theme, but the whole soundtrack) was Icewind Dale. I remember how much I liked all the different musical pieces they had for that one, and there were at least two music pieces (again, not the main theme, but just isolated ones from the soundtrack) that I thought were awesome.
