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

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