Mendes continues his climb from Vine star to chart-topper with his second airplay No. 1.

Shawn Mendes earns his first No. 1 on Billboard's Adult Pop Songs radio airplay chart (dated Feb. 6), as "Stitches" lifts 2-1. The track tops its second airplay tally; it first ruled Pop Songs for two weeks in November.

Mendes' new leader (and first entry) on the Nielsen Music-measured Adult Pop Songs chart is from his debut full-length album, Handwritten, which debuted atop the Billboard 200 last May and has sold 342,000 copies to date in the U.S. "Stitches" has sold 2.1 million downloads. Mendes first arrived with 2014's The Shawn Mendes EP, which debuted and peaked at No. 5 on the Billboard 200 and has sold 103,000.

Meanwhile, Mendes bookends Adult Pop Songs, as "Stitches" follow-up "I Know What You Did Last Summer," with Fifth Harmony's Camila Cabello, debuts at No. 40.

Mendes' list of achievements, thus, grows upon crowning Adult Pop Songs. Since first building his audience by posting videos on Vine, the 17-year-old has also opened multiple dates on Taylor Swift's 1989 World Tour.
