Romeo and Juliet themed songs?

Alright, so I'm writing a Romeo and Juliet themed book, and I was wondering if there are some songs about a Romeo and Juliet love. It's about a werewolf hunter falling in love with the very thing she hunts, a werewolf. Anyway, any songs to match the theme? I could care less about what genre, just as long as it's not scream-o (that's how you spell it right?).
