Josh Greenberg, the co-founder of Grooveshark, was found dead on Sunday at his home in Florida. The cause of the 28-year-old’s death is still completely unknown, as the entrepreneur’s mother, Lori Greenberg, told the paper that he didn’t have any health issues, and supposedly there was no immediate evidence of foul play, injury, or drugs.

Greenberg’s mother stated, however, that the decision to end the once-thriving business didn’t lead her son into a depression, as he was actually “more relieved…since it ended the lawsuit that had been hanging over his head”.

The Gainesville Police Department confirmed the news on Twitter, stating there was “no evidence of foul play or suicide”. The service emerged as the music industry transitioned from rampant illegal downloading to legal streaming.

“They are as baffled as I am”, she said.

Greenberg co-founded Grooveshark with Sam Tarantino as a 19-year-old University of Florida freshman.

The medical examiner was performing an autopsy Monday morning and would know if there were obvious problems with Greenberg’s heart or brain, otherwise, toxicology results would be done in two or three months, Lori Greenberg said. The music streaming website, which quickly became a thorn in the side of music labels and record companies looking to clamp down on music piracy, was shut down for good on April 30 at the close of a lawsuit and settlement. But despite best of intentions, we made very serious mistakes. That was wrong. We apologize.
