After one initial listen to Rihanna's leaked Rated R album, here are the first three words (kind of) that came to mind to describe Rihanna's sound this time around:
Mad-as-hell! Potty-mouthed! Poserish?
Her Bajan accent is back! Just saying... Standout songs: Russian Roulette, Hard, Te Amo, Rude Boy, Cold Case Love ... it's hard to even see what songs on her album can stand as singles. Basically, Rihanna to Rated R is what Kanye West was to 808s. Sounds that are different, but fully expressed their emotions at the moment.
