When I bought the album, it blew me away! My personal favorites are: Stupid in Love, Hard, Te Amo & Russian Roulette. The only song that is not really going in my ear is Photographs. But that's a matter of taste. The time now is already 3 years since the album came out and I hear it up and down still.
My placement of all Rihanna albums:
1: Rated R 2: Loud 3: Good Girl Gone Bad 4: Talk That Talk 5: A Girl Like Me 6: Music Of The Sun
