Grooveshark's co-founder Josh Greenberg has died at 28. He was found dead at home in his bed by his girlfriend on Sunday. The Gainesville police department stated in a tweet that there is no evidence of suicide or foul play. His mother said in a statement today that Greenberg had no health issues, and that the police had advised her there were likewise no signs of drugs being involved. Grooveshark recently underwent legal turmoil, but his mother reports that he was “more relieved than depressed” over the service’s closure.
