I was able to install it. Now when trying to play a song whole kodi freezes

I have no clue what's going on with your machine. It's working fine at multiple of my machines.
Make sure that you have installed version 1.1.16 through my repo and just to be safe restart your computer afterwards.
If the playback is still failing after that, I need a Kodi debug log captured after you tried the playback.

Can you browse the menus of the addon successfully ?

As you asked me I already posted the log in previous page. Now trying several times I realized that sometimes the playback starts, but the streaming is very bad and slow and playback keeps stopping and I hear cracking sounds! I believe to think that the problem is about the port used by this type of connection. Can you explain me what type of connection does the addon use to connect to Spotify servers? Maybe could be blocked by my isp? I connect through a Vodafone Wi-Fi hotspot with captive portal login... ( I made a script to auto connect that runs every five minutes..)
