Looking to permanetly shuffle your Deezer playlist? Use the following tool to do it. Once you authenticate this app with your account on Deezer, you will see all your playlists listed.
Someone asked me to create a similar tool for Deezer as the Spotify Playlist Randomizer I created previously. Looked it up and they had an API available to hook into.
Works more or less the same as the Spotify Playlist Randomizer one.
