Fetty Wap’s leap from rookie to renegade is one of 2015’s biggest stories. The rapper goes hard on every line and his cascading voice grabs the ear with the tenacity of a pit bull. “How We Do Things” and “No Days Off” are squad anthems celebrating hard-won victories. “Trap Queen” is the album’s centrepiece—revealing that behind every crumpled and conflicted dollar bill is a triumph of will. Filled with iridescent hi-hats and rolling bass kicks, the album backs up the social media chatter—all the Likes and Shares. Not since Nelly has a rapper made hip-hop so contagious and singable. And the scary thing is Fetty’s just getting started.
