Best: Rihanna, Take Two
Rihanna's second medley of the night was a party — quite literally, as revelers who were ready to move along with whatever songs she served up surrounded her onstage. Opening with a flip of the taunting "Rude Boy" that incorporated the beat from Chaka Demus and Pliers' spiny dancehall crossover hit "Murder She Wrote" (itself lifted from the Maytals' "Bam Bam"), RiRi led her guests in a sweaty run through "Rude Boy," followed by the playful "What's My Name?" and the sinewy "Work." Drake didn't show up for the latter, but the energy Rihanna and her phalanx of partiers had onstage more than made up for it.
