There is nothing to like about Rihanna's continued relationship with Chris Brown, but if 2012 did produce one great thing with them together, it was this collaboration from RiRi's album 'Talk That Talk.' An absolutely simple song, this is just a ferocious beat over some nonsense lyrics that liken eating a birthday cake to the kinds of things that adults do in dark rooms to celebrate in their birthday suits. We never thought that repeating "cake, cake, cake, cake, cake," in the lyrics would be just as good as eating it. [WENN]
