The song is sung by Switchfoot.<br />
I think that the song is about this girl, " Daisy " who feels she has to fight against the world alone. He's saying that if this sh*tty world doesn't care about you, don't bother and move on to better things.
Switchfoot sings it. I'm not sure how to interpret it. In a way it sounds like he's telling her it's ok to just let it go and die (perhaps she has terminal cancer?). It could also be taken as a young man trying to convince his girlfriend to give up her virginity or maybe just to stop being such a worry wart. However you take it, it's an odd little tune.
It's a dude singing and its bout the devil trying to talk into su isi de ?
