Last summer Ryn Weaver teamed up with all-star hitmakers Benny Blanco and Charli XCX for the out-of-nowhere hit "OctaHate." It’s since racked up nearly 3 million plays on SoundCloud and—along with her short EP, Promises—made Weaver one of the most intriguing prospects in pop. Anyone would have a tremendous head start with Blanco and Charli XCX on their side, sure. But that boost combined with Weaver’s vulnerable songwriting and powerful voice make her pending EP as safe a bet as you can find. —Ian Servantes
