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

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