the song sounds kinda like Sonata Arctica (or that was my first and only impression of it) so it's really guitar heavy. At one point I managed to make out these words "I am the enemy within".
I checked around google and it is not the song by Rush, Acid Death, Arch Enemy, Cherry Poppin Daddies, Biomechanical, Morifade or Death in June... lol, yeah; it's an elusive little bugger.
Help would be greatly appreciated!
