It's a girl singing, I thought it was Zooey Deschanel at first, it kind of sounds like her. The song starts off with a piano like chord playing the same through out the song. It is a melow beat. It's not loud enough to hear sometimes but i hear "i didn't" a lot and "fly away" or "fly" and she says "i love you more" and "you you you you"
i have been googeling like craaazy!! i hope someone knows this song !
