Prince.. The icon.. The musical genius.. The innovator! He should be in full control of his discography, he is truly in a leave of his own! And that performance feat Beyonce at the Grammys is so amazing/memorable!!! It takes a true musical genius (Beyonce) to compliment a musical genius as big as prince and KILL IT!!! Katy Perry, Lorde, Rihanna, Ciara, Lana Del Rey, Sevyn, and a vast majority of the rest of the girls COULD NEVER!!
