“Sex sells” doesn’t explain everything in the world, but it does make sense of about 95% of things. Last night Rihanna hit Saturday Night Live for some leg-spreading, crotch-slapping, and body-rubbing. While this was going on she also sang songs. It was beautiful, and music fans who normally complain about Rihanna’s lack of originality or musical talent watched like, “Fuck it, who cares, YOLO, etc.”
