I don't get why people think she is so talented

Probably because the definition of 'talent' has changed so much these days Rihanna finally looks like a breakthrough artist.
Anyway...her first single is a ballad so i'm predicting around 250K because of the hype created by the 'Chris Brown hit me ERA'.
I hope she has better singles specially up-tempos & it seems she has been taking vocal classes. So hopes are up.
