@BEY'knight :

I really don't know whos MJB ! but based on this site ! She's a respected r&B artist !

Sales now don't reflect if the music is good or bad ! Sales in 2012 reflects how strong your fanbase is !
Abd R&B consumers are not that strong now !!

but I think Rihanna gonna win this one ! that's my opinion ! I do not see any buzz or hype about MJB ! but I see it with R !

I will check her stuffs Though ! I will first start with trying to find a greatest hits album of her to see what she has to offer ! I will see if I'm going to be a fan :)
