I absolutely despise both Drake and Rihanna. Drake, mostly for plaguing the world with YOLO and generally being an uninteresting musician (although he does have some good lines in his collaboration stuff) and Rihanna for having some of the blandest sounding songs on radio, her inability to go away and not release an album every year and, most importantly, being a terrible role model to her fairly young fans in regards to her relationship with Chris Brown, crawling back to him despite him not showing any remorse for his crime.
Despite all of this however, I think the song they released together last year, Take Care, was one of the best songs of the year. The chemistry they pull off is brilliant and powerful, with Rihanna being especially good, tapping into the same regret that made her chorus on Love The Way You Lie so good as well. That and the production on the song being spot on also
