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.
It is switch foot but I think it's not as much about dying as it is letting go of all that others say you should hold close and what should everyone, someone, says should be the most important. This is your life, live it as you believe it should be lived.
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 ?
