Music lovers are buzzing over the 22-year-old British singer's rendition of Whitney Houston's 1985 hit, "How Will I Know." Part of the song could recently be heard on "Grey's Anatomy," and now there's a full-length version from Smith's studio visit to SiriusXM.
During the performance, Smith slows down the Houston classic, showing off extraordinary vocal chops in a refreshing new take on the song. "How Will I Know," which appeared on Houston's self-titled debut album, became her second No. 1 single.
