Kyle has plenty of reason to smile these days. After striking gold with "iSpy" — his Lil Yachty–featuring hit brimming with goofy charm — the rising Cali rapper is plotting his next big moves. He's full of promise and unbridled positive energy, but he wasn't always so self-assured. In fact, as the 24-year-old recently told MTV News, finding his own voice was a huge challenge."When I first started rapping, I just rapped about what I was taught to rap about. You know, guns, packs, big booties … things like that," Kyle — who is MTV's Push: Artist to Watch for the month of June — told correspondent Meredith Graves in a recent interview. "I was making this one song, and what I had just written was so unbelievably not me that I rapped it and laughed."
