Chris Brown found fame with POP music and Urban music. Sure his songs have elements of R&B but nearly every song nowadays have that. Unlike say R. Kelly, Usher, Beyoncé, whatever, who found fame IN R&B music, but the the latters branched out to Pop and dance.

Doing pop music isn't bad though. I never understood that issue. If ur a fan of an artist, u should enjoy them branching out instead of doing the same shit over and over again. AKA why R&B died past 2008 in the first place.
