Spotify for Linux is a labor of love from our engineers that wanted to listen to Spotify on their Linux development machines. They work on it in their spare time and it is currently not a platform that we actively support.
Not enough paid linux users. Simple as that.
For what it's worth, the software works well on Arch in my case.
This reply may already have been given, seeing as there are 104 replies, however: The simplest fix is to install Spotify the 'old way' by adding spotify's deb repository and NOT Snap. I have tested and the apt install does not display the freezing issue for me.
