What are your favourite songs that are not from any of the musical versions, but they make 你 think of the phantom of the opera?

Let's see... Breath of Life 由 Florence & The Machine, Demons 由 Imagine 龙 (for Erik/Meg pairings... I know, I'm hopeless, I'm obsessed 由 E/M, I need help), Sing 由 My Chemical Romance... and probably a lot more, but I can't remember them right now.
