Josh Greenberg, the co-founder of the recently shuttered music streaming website Grooveshark, was found dead in his bed by his girlfriend at his Florida home, local police said Monday. He was 28. There was "no evidence of foul play or suicide," Gainesville police said via Twitter. The streaming service closed in April after years of legal battle with several major record labels over copyright violations. Greenberg's mother Lori Greenberg told the Gainesville Sun she didn't believe her son had any health concerns, and that he "was excited about potential new things that he was going to start." Greenberg's mother said the medical examiner's autopsy found no explanation for a cause of death, but toxicology results could take up to two or three months.
