Recently i've gotten into watching Attack on Titan and this one track, Dark Side of Power, is just BADASS!
It's very reminiscent of the Bay Town theme when you encounter an opponent, you know? In fact play Dark Side of Power over some WotM gameplay footage (with no volume) to replace the track and watch the cutscene/fight to know what I mean! :D
Feel I should also mention this should've been played during the final battle. :3
