teairra mari was ghetto and the pop world dominates and eliminates ghetto artist. rihanna is this red pop island queen. she is so much sellable. she is on trl cuz she has white audiences and bet because black people loved them some umbrella. point is, is that rihanna is wayyy more versatile and diverse teairra has a very urban voice and thats not marketable these days. rihanna has a pop/carribean voice that draws people 2 her, very unique! but no doubt teairra had more talnt tho!
