Smule co-founder, CTO, and COO, Ge Wang, sat with Billboard at the Billboard Mobile Entertainment Live The Music App Summit to discuss a wide range of topics, including his experience creating "I Am T-Pain," his thoughts on the possibility of Smule being acquired, the future of the app space and more. It's a must-watch video and Wang even shows off his music chops about three minutes in when he plays "a little ditty from Zelda" on the Ocarina app.
