Actually I think Wiz has way more potential than SB EVER did based on his previous work. Roll Up is an obvious reach for a pop smash. And it doesn't come off well with his "accent" and the singy chorus. I mean I understand the thought and intention but the execution is bad.
and Ke$ha, and Britney and Katy and just about every other Pop female artist
Not kelly Clarkson, Leona Lewis, Dido, Pink, Bey and countless others
Plus Brit didn't built a career out of it, only her recent albums follow that trend.
