I always listen to "Annie" by Safetysuit. It's about a girl (named Annie) who by all means, is no super model when it comes to looks, and yet she means so much to this one guy who's telling her that "looks don't make the world to round"/that looks don't mean everything. To this person, her smile lights up the room and she means the world to him.
Overall, we're all Annie, wanting to be beautiful yet not realizing the beauty we already have.
In my personal opinion, it's a real self-esteemed booster
