Dick and Barry from the film High Fidelity may epitomize the record geek stereotype, but there is something undeniably charming about someone so integrated into the music world that they are able to recommend new bands based on what they know you like. Sam Tarantino, CEO and founder of Grooveshark, decided to bring that same mentality to the internet, complete with the mix-tape swapping. File-swappers had been already doing this since the days of Napster, but Grooveshark has one big difference: it’s legal.The Grooveshark music library is made up entirely of user-sourced content, which means the tracks have been uploaded by fastidious fans. While some bands like Pink Floyd have refused to let their music be uploaded in this way, the fact that the tracks can’t be downloaded keeps users from walking away with free music. Instead, users can make playlists within the Grooveshark site itself, which they can come back to and listen at will. Grooveshark also features a music recommendation service through a customized radio based on what’s in your library. You can also add users to your profile and get notified when they create a new playlist, so if you find your own Dick or Barry on the site, you can stay connected with them.Grooveshark is offered by the Escape Media Group Inc., located in Gainesville, Florida. Initially, the site did allow paid downloads, giving uploaders a percentage of the profit for any songs they added. That function was discontinued in 2008, and the new site is gaining momentum. With currently 400,000 users, the online population was growing by 2-3 per day in April 2009. If you’re looking for that record shop feel without leaving the safety of your own house, catch a wave and check Grooveshark out today.
