The Grammy-nominated musician is helping Myspace get its mojo back.

Lots of stars hold fancy titles (creative director, chief innovation officer) for coolness-starved brands. But Kenna wants nothing to do with honorary positions and no-show jobs. Last year, the 34-year-old musician—whose career had already taken him from his birthplace in an Ethiopian village to a 2009 Grammy nomination for "Say Goodbye to Love"—accepted a job with Myspace at the urging of his good friend Justin Timberlake, a chief investor in the site's January relaunch. Kenna had one demand: Use him—really use him—or lose him. As the company's Chief Vision Officer, he's heavily involved with the creative team in building new tools for artists to connect with audiences. He came to the gig honestly: A seasoned codehead, he was one of the first musicians, in 2003, to recognize Myspace's potential as a buzz builder (it was also, he admits, "a way to find chicks"). And while the site has long since been supplanted by YouTube as the Internet's jukebox, "artists are still using the platform to promote themselves," Kenna observes. That's why he believes it still has unrealized potential as a means of connecting users with content, whether it's songs or art or video or something else altogether. "I couldn't care less if people come to Myspace to find their friends," he says. "I want people to come to Myspace to find themselves."
