It's hard to say what I like more about this song. Is it the creep factor of the intro combined to the broken drums and staccato choirs? Or when the beat and strings come up?
No, I think it's at 1:05 and 1:14, when the electric guitar first comes in to deliver some awesome, and then the organ bursts into the place carrying more musical badassry in its bicep's triceps than Blood Bath and Fire Cross combined.
The forest of illusions bit after is creepy and nice, too, but after that part, it's a bit like Freddy coming into your house with a machete after Chuck Norris and Rambo went apeshit at the furniture.
Either way, this is made of awesome and win. I'd put 10/10, but 10 is an entirely too small number. More like 10^10/10. Hell, /1, because I don't feel like dividing the score.
