"This is the most selfish song i ever heard. " I don't know what's selfish about this. She just sings about how much she wants to be loved by this one person. I think if you have ever been truly in love without being loved back you can relate to how this feels..
I still love this song though it fit more when I didn't have my wonderful boyfriend who loves me, needs me, couldn't eat without me, would be spending the rest of his nights awake without me,.. :D  anyway it's incredible how this song makes sad
