I have to agree with 3f az on this one it is really a amazing song and it just happend to fit perfectly with twilight. He is talking about this beautiful woman that he is so very highly attracted to and she is slowly realing him in with her beauty and he can't try to stop because he loves her far too much so he says "i cant fight the devil so let me sign" and I don't like it when people say that people are never going to meet robert pattinson and just to let you know that I actually met him at a twilight book signing and he said I was cute. I even have his autograph. Ha!
