Nothing like a good sob on a weekend: Sam Smith covered Whitney Houston's "How Will I Know" and it is very, very good.

A snippet of his cover appeared in a recent episode of Grey's Anatomy, but a full live performance made its way onto the Internet on Friday, courtesy of SiriusXM. Houston's original version was released in 1985 and hit No. 1 on the Billboard Hot 100 on February 15, 1986.

Smith's debut album, In the Lonely Hour, was released on June 10 and is projected to arrive at No. 2 on the Billboard 200 albums chart (with 150,000 to 160,000 copies) for the week ending on June 22, second only to Lana Del Rey's Ultraviolence.
