LOL Rihanna has not sold no damn real 50 million albums worldwise. Not when she is barely over 10 million copies sold in the uSA. It´s just impossible. Adele sold with an album what Rihanna did in her entire career. That´s all. For anybody with a brain and some type of correct perceptive system, it is easy to see the difference. Rihanna has never been universal as to move huge album units. End of story.
