Boy stop the delusions. Rihanna is pop and that´s it. She trying to act liek a rock star doesn´t make her a real musician. Among the two, the one who has changed genre (successfully at that) has been Gaga with a pure Jazz album. Rihanna has not changed genres. Stop the delusions. Diamonds is a pop ballad, in case you were counting that and as a different genre LOL
