Right there is WAY TOO MUCH hate on this sight, first of all Rihanna is an R&B/urban artist, when she first came out with Pon De Replay she was considered to be an reggae/dancehall/R&B artist due to her thick Caribbean accent and her album Music Of The Sun which blended R&B/ reggae/dancheall/urban/hip-hop together, then came her second album A Girl Like Me which kept much of the musics tyles of Music Of The Sun but added a bit more of a dance vibe, her third album Good Girl Gone Bad was a mixture of R&B/soul/dance/club music and a departure from her reggae roots, her fourth album Rated R was in fact her most urban album back then with her new I Don't Give A F*ck attitude and a mixture of R&B/hip-hop/dubstep/reggae and her heavily using her Caribbean accent (can be heard on Wait Your Turn/Rude Boy and Hard) in 2010 her music took again a different turn heavily leaning towards an R&B/dance/hip-hop sound with a mixture of other genres such as her "bread and butter" reggae/dancehall (Man Down, Raining Men) and rock, then came her Talk That Talk album which I think could sum 2011 in music up with a mixture of LMFAO here, David Guetta there, a pinch of Pitbull, two tea spoons of that thing GaGa and blend of R&B/dance/EDM/house/dubstep/hip-hop and a couple of reggae songs such as You Da One and Watch N Learn, her recent album Unapologetic is in my opinon a mixture of a Good Girl Gone Bad/Rated R/Loud/Talk That Talk the overall sound of the album is R&B mixed with genres such as hip-hop/EDM/dubstep/reggae/dance, but getting back to whether Rihanna is R&B or pop, she is a popular R&B singer who is not afraid to dabble in other genres I do think she is like the rest of the artists nowadays such in this dance/EDM/dubstep phase that is dominating the charts, I dunno if we will ever see Rihanna going back to her R&B/dancehall roots but she is most definitely an R&B artist, any music shop you go into will have her under R&B, her Myspace page many many years ago before it alphabetized the genres had in fact R&B first followed by reggae and pop, of course then when Talk That Talk was dropped, reggae was removed and replaced with hip-hop. If you guys wanna argue out what she is good luck to you but you must know the facts.
