2016: The Year in Charts

Watch Shawn Mendes Perform 'Treat You Better' and 'Mercy' at the 2016 AMAs

Shawn Mendes took the stage tonight at the American Music Awards to play two of his biggest hits from sophomore album Illuminate.

Performing isolated on a diamond-shaped stage with faux-fireworks going off on the screen behind him, Mendes delivered a full performance of Billboard Hot 100 top 10 smash "Treat You Better," before segueing into a more abbreviated, piano-led version of latest single "Mercy."

Watch the performance above.
