The Grooveshark system works on the basis of a peer-to-peer music sharing system, Greenberg said. Users can upload their personal music library to the Web site.
To legalize the process, the user must buy a song if they want to add it to their collection, he said. Part of the profit is then deposited into the account of the person who uploaded the song to Grooveshark.
In this way, the sharing of an illegal music system is paired with the legalized purchase with the added benefit of compensation, Greenberg said.
