There's something about this song that gets me. It's really great. Like, it makes you think of all the evil, and all the darkness in Malefor's character. And the sadness in the song now and then, the violins, really makes me think of how great he was in the eyes of The Guardians, and his fall.
It's somber, calm, menacing, has a nice mix of deep harrowing notes and shrill dissonant harmonies, the choirs really do amazingly... Say about TloS what you must but it achieved an atmosphere I have not yet seen anywhere else... The OST is just that genius... Wish these games would've gotten the time and budget to iron out the flaws...
