Well, to be brutal, I am usually a HUGE fan of Caribbean artists making it internationally.. including Sean Paul, Bob Marley, and the plethora of Jamaican producers behind much of modern-day hiphop..
But Rihanna, I think, is the pits... she has no showmanship whatsoever, doesnt get anyone's attention on stage, and her voice is mediocre at best...
I would consider her fit for a girl next door that likes to sing, but she is no international pop star material, unlike people like Christina Aguilera (for her amazing voice), Madonna (for her incredible stage presence) and lady Gaga (for her incredibly unique and innovative artistic sense)... Rihanna just has none of these,
But! She has a nice Barbados accent.. i love Barbados accents
