Shameless plug, but we are doing exactly that here at http://milq.com http://milq.com. We are attempting to organize the world's media into collaborative playlists, which you can then subscribe to for a feed of content uniquely tailored to your personal taste. Subscribing or dismissing a playlist helps us recommend better content to you. Give it a look! :)
