I'm a fanboy, so sue me.
I really love this song as it's the absolute best incarnation of 'The Beast' thus far, and there's an easter egg in it. At the very beginning where you hear the chanting, it's actually just a really elongated word. If you listen closely, you can hear that they're actually saying "Hallelujah." Just the place in which this song was used in Rebuild 2.XX makes this song infinitly better, and this is a thing that can't be un-heard. It's simply wonderful.
