Grooveshark is a new social music website that is currently in closed alpha stage. I was able to get an invitation to the system and would like to write about it here at ghacks and also give out some invites to Grooveshark to a handful of lucky readers.
Grooveshark works basically the following way. You start an application on your computer and decide which music folders you want to share with the community. This application has to be running in the background to be able to share and listen to the music on the Grooveshark website.
