in the main circle http://mixlr.com you can choose what broadcasters you want to listen. It's very handy, lot more compact and broad at the same time than stereomood. Great place to listen some great live sets! You can leave comments on the chat, follow the radios, broadcasts you want, see the profiles, see the stage if they have some video also of the session, and see how many other people are listening to the same channel! This is just awesome! And all super clear and easy! And you can also broadcast yourself if you want to, which is super cool!
