This extension hooks into Deezer to play a random track from one of your favourite artists.
By setting a Deezer User ID, this extension enables a proper shuffle feature across all favourited artists. Deezer also has a service called Flow, which is similar, but I found that it was very weighted for my tastes, as I would be listening to the same 30 songs over and over. Using this extension will provide a button in the URL bar for the Deezer website that you can click to shuffle. The extension is not limited to your own personal User ID. If you want to shuffle based on someone else's musical tastes, plug in their User ID instead! Be sure to set the User ID in the extension options before shuffling, or else you will be listening to the default user, which is myself. :)
