I have to disagree with the "positive message" this song is sending. It still is only all about a girls looks rather than anything inherently about her personality or brains. It also is promoting low esteem. You are beautiful because you don't know you are beautiful? Wouldn't it be better if all adolescent girls knew they were beautiful? The girl the song is about is supposedly very attractive, since "everyone" can see, but doesn't seem to believe it. Is this really the message you want to send to your teen or pre-teen daughter?
