Hi nickvas19,
There are some problems with Spotify, search the forum for details.
What you should get is a list of your own playlists, the playlists which you follow will not be shown. It is very slow and takes quite a while to load the information. But it works.

P.S. On 20-12-2017 Spotify announced that they have given permission to the Lunix foundation to pre-install the Spotify software in the standard Linux distribution

So, there is a good chance that the current Spotify problems will soon be fixed and the possibility of more features.
Also thanks to Spotify for the Christmas present for all Linux audio enthusiasts.
