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

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