Sam Smith and Ed Sheeran -- young Brits in search of love and slightly better songs

There's a new viral video making the rounds featuring British R&B supernova Sam Smith performing a slowed-down live cover of Whitney Houston's "How Will I Know." Smith's version is a funeral dirge, slow and inconsolably sad. He isn't reinventing this once-joyous song; he's sifting through its wreckage. The video is a revelation -- Smith's voice is an increasingly supple and wondrous instrument -- and also a mistake. Some songs weren't meant to be sad.
