FineTune.com

FineTune.com -- this is what epitonic.com could have become. FineTune has it all, shared playlists, regular radio, music preference based radio, and a huge catalog. I'm waiting to see how this will play out -- it's hard to imagine someone being faster than Pandora at getting new music in the catalog. And musicovery has that multi-directional next button. They're all good.
