Best: Sam Smith and Mary J. Blige Stay With Each Other
By this time last year, Sam Smith and Mary J. Blige had both appeared on Disclosure records but otherwise had little in common. They've since collaborated, offered mutual inspiration and now, performed together on the Grammy stage. And where those Disclosure records showed how naturally both singers could align themselves to a groove, these five minutes proved what they can do when given the chance to let loose. Smith, who readily admits his love for R&B singers like Blige, seemed to tremble for a moment, but from there he showed no sign of nerves, adding a delicate touch to what is now the best alternate version of "Stay With Me." Sorry, Darkchild.
