Despite it's... infamous reputation related to a certain shock video, the song itself is quite good once you get past the first seconds. You could even replace "Two Become One" with this song and it'd work just as well (especially for the Act 1 Bad Ending). 1:22 minutes it, it even reminds me of the game's musical style, with it bringing back memories of "Painful History".

"The Light" by Disturbed. It fits Emi's route so well that it inspired me to create an AMV - which is still a work in progress but it'll be done Soon^tm
