Tinashe's fourth-quarter drop, Black Water, setup the LA-singer for a big 2014. Today she starts making that so, teaming up with self-proclaimed Man of the Year ScHoolboy Q and DJ Mustard for "2 On," an early tease for her forthcoming RCA debut. DJ Mustard's beat is a little more lasers at the club and less the laptop glow of Black Water, but Tinashe still brings her charge and easy confidence: Get faded, turn up with the bad boys. Live fast, die young, that's my choice.
