A few years ago, Inji was at a crossroads. The New York-based, Istanbul-born musician had recently departed the Wharton School of the University of Pennsylvania with a degree in finance, and found herself on a graduate scheme at a management consulting firm in New York City -- while making dance-pop bangers on the side. "It was a real everything-is-falling-apart time of my life," she recalls. "I was crashing out."

The result of this freakout is captured on "Teen Angst," the brilliant, brassy opening song on her mixtape Superlame, released at the end of October. (Suffice to say, she turned to music full-time.) The song was the product of her getting in the studio with producer-of-the-moment Zhone, the mastermind behind Troye Sivan's "Rush" and Demi Lovato's "Fast." After hours spent looking for the right starting point, Inji took the mic and just started freestyling over a stomping club beat, chanting, "I woke up pissed off on a Tuesday / I said, 'Fuck this shit!'" Inji explains that the words came out as a furious stream of consciousness, remembering the aftermath of recording the track with a laugh: "I was like, 'Oh, I see. I think this is what the album's about.'"
