Massey's specialty continues to be merging the boutique-label heritage of Island with modern chart savvy. Mike Posner and Shawn Mendes drove pop down a singer-songwriter lane, with a Grammy nomination for Posner's "I Took a Pill in Ibiza" (1.6 million tracks sold, 396 million on-demand streams) and Mendes generating 892 million on-demand streams in 2016. Also on the British-born executive's watch, Demi Lovato and Nick Jonas fully shed their tween pasts. Jonas scored a No. 2 debut for Last Year Was Complicated on the Billboard 200, and Lovato netted her first Grammy nom for Confident.
