Before there was Spotify, Grooveshark lead the pack of online music streaming services. It was one of the first sites of its kind that let users play any songs they wanted, with no restrictions. Thursday, the company shut its doors and will not be making a return, according to Business Insider. In its early days, much of Grooveshark's success came from its use of unlicensed music on its site. Consequently, one of the main reasons the site shut down was part of legal settlements with copyright holders, such as artists and music labels, that own the rights of a majority of the music featured on Grooveshark. Business Insider explained that in 2013, Grooveshark settled suits with EMI and Sony (NYSE: SNE). However, with the recent rise of paid music streaming services, like Songza and Spotify, Grooveshark was unable to keep up with competition on top of its legal issues, which it is openly apologetic about. "We failed to secure licenses from rights holders for the vast amount of music on the service. That was wrong. We apologize. Without reservation," Grooveshark representative stated.
