Didn't Chris Brown Write Disturbia?

Up and coming rapper and rumored Rihanna jump-off Drake says, “I’m actually writing for Rihanna right now. I guess I’m living a dream. I enjoy a challenge. I’ve never in my mind felt like, ‘Oh, I could probably write something crazy for Rihanna.’ That wasn’t my first thought. But being put up to the task, we’re coming up with some special stuff. It’s crazy, man. All I could do is smile. It’s nice.” Spotted here via here
