Grooveshark, a free music service has added social networking features and some design changes aimed at simplifying the site and emphasizing music discovery. Grooveshark is a web-based music application built for anyone on the internet to listen to music on-demand at no charge.

Users have the ability to listen to single songs from over 15 million songs, save playlists. Grooveshark also allows artists and record labels to promote themselves through the application with rich site takeovers, advertising based on a slew of targeting and demographic data, and getting their music straight to the ears of the music fans most likely to love it.

Grooveshark Creative Director John Ashenden and the company’s SVP of external affairs Paul Geller told GigaOm that the updates is about building a solid base for some big future changes.

Ashenden further stated that the new changes is “the first real push from Grooveshark to connect music fans with music fans.”
