"They are as baffled as I am," Lori told the Gainesville Sun. Josh Greenberg became popular after he co-founded Grooveshark with Sam Tarantino in 2006 while still freshmen at the University of Florida. At 19, Greenberg went on to become the start-up's chief technology officer.

Things took a bad turn in April while the company was at its peak. With approximately 40 million users monthly and 145 employees during the time, Grooveshark had to shut down after $17 billion infringement lawsuits with Universal, Sony, and Warner Music were filed. According to the copyright charges, the company had operated without licensing its music.

Part of the settlement requires Grooveshark's parent company, Escape Media Group, to pay $75 million to the labels, according to Variety.

"Despite [the] best of intentions, we made very serious mistakes. We failed to secure licenses from rights holders for the vast amount of music on the service," Grooveshark said in a statement in closing the site.

"That was wrong. We apologise. Without reservation," added the statement.

Josh's mother said that despite the company's downfall, he appeared excited of future endeavor and that her son was not depressed.

"He was excited about potential new things that he was going to start," she said. Aside from Grooveshark, Greenberg helped to launch a scheduling app called MaidSuite for cleaning companies.

He has also helped launch Gainesville Dev Academy, which teaches computer programming. Greenberg also helped aspiring entrepreneurs with the Summer with the Sharks internship program, with classes held at Grooveshark University. He is also a partner in the Founders Pad business incubator and became a founding member of the Gainesville Area Chamber of Commerce's Gainesville Technology Council.
