The difference between Rihanna and Madonna i that Madonna has a brain and is a great performer...She had to be to stand up to MJ and Prince in the 80's. That was why she is successful...She tried hard to be one of the kings and actually surpassed both of them. Yes they are more talented naturally, but Madonna is smart. She didn't become a recluse or let fame get to her head...Or become a drug addicted pedophile (sorry, but I care for children).
