Plz suggest a song which describes the beauty of a girl...!!!?

Well, this is basically your call. You must like a certain genre of music or a favorite band. Or you may even have a song that you can relate too. A good song I like for this particular situation would be a Bob Dylan composition from his Infidels record titled "A Sweet Heart Like You." But there are many songs or bands that can cover this. I personally like Queen for this sort of stuff like "Love Of My Life", "Your My Best Friend" or "You Take My Breathe Away." They have some great stuff. Well, good luck with your proposal.
