Note: all of the above require an arl = arl cookie after logging into (free) deezer account. i.e. F12 in Firefox, storage, cookies, arl, then copy the content. The cookie is valid for 3 months.
Entering the arl cookie in the web interface stores it per client. Storing it in ~/.config/deemix/.arl and using –serverwide-arl flag can use the same for all clients.
