Sure it's launched plenty of successful music apps, but to us, Smule will always be the company that gave us iPhone-based AutoTune in the form of I Am T-Pain (which we managed to try out on half of They Might Be Giants). Obviously, the Bay Area developer is looking to be a lot more. In fact, it's opening itself up to the web in the form of a social network that'll let visitors peruse its one billion or so user-generated songs. You can create playlists of Smule-created music and find folks to collaborate with for cloud-based jam sessions. The network opens today through Smule's site.
