If you don't know Sam Smith, let his cover of Whitney Houston’s "How Will I Know" be the ultimate introduction. The 22-year-old British crooner, who just released his highly-anticipated debut album In the Lonely Hour on June 17, performed a gorgeous version of Houston's upbeat pop original while at Sirius XM radio, and we can't stop listening to it. Who knew that "How Will I Know" could be so heartbreaking?

Watch him perform the song below, and get ready to listen to it on repeat all day long. Happy Monday!
