Best Cover: Shawn Mendes Sings "Use Somebody"
In the middle of his set, Shawn Mendes wailed the emotive intro to Kings of Leon's "Use Somebody," stunning a vast majority of the crowd and leaving a handful of younger fans who were unfamiliar with the track confused. Nevertheless, it was a short and sweet tribute to one of Mendes' favorite groups, and it highlighted the teen star's pop-rock capabilities and vocal chops. Along with performances of hits like "There's Nothing Holdin' Me Back" and recent singles like "In My Blood," the Canadian singer-songwriter proved that, while he was "totally" intimidated to play the fest, he had nothing to worry about. "This is really cool for me because this was one of the first festivals I went to and I remember thinking, 'Wow, it would be cool to be on that stage,' and now I'm on that stage," he told the crowd.
