Grooveshark allows you to build a library of music, favorites, playlists, follow friends, find and buy concert tickets from Artists page through SongKick (YC 07), listen on your mobile device if you have Grooveshark Anywhere. Their other paid plan, Grooveshark Plus gives you access to early features before they're rolled out to the normal users like their desktop client, visualizations, Last.fm scrobbling, no limits on library + fav size and more.

If they can find a way to fix their content quality problem and licensing issues with the RIAA, they have a really bright future. They're the most innovative company in the space right now and I think it would be a damn shame if they were forced to close due to different recording companies constantly suing them and turning back on their settlement deals. Having to deal with EMI, Sony Warner MG, Universal and their ilk separately is part of the problem as well. The reason their iPhone app got pulled from the App Store[1] was because UMG filed a new copyright infringement lawsuit against them Jan 2010.

You have to understand they function quite similarly to how Youtube works and is obligated to follow the DMCA.
