AccuRadio is comprised of hundreds of channels of music, spanning over 60 genres. There are hundreds of channels that you can personalize. You can skip songs you don't like, delete artists from the upcoming playlists, and mix various genres together in a single channel.
Each one of these has its own playlist of artists and songs. To start listening to one of these channels, click one of the blue tiles you see around the site. That will launch a new player window where you can control the channel. LINK: The Presurfer
