I just removed my flatpak install of spotify, installed snapd and through snapd I installed spotify == not working spotify which throws a coredump => me being a sad panda. :D
snap run spotify
(spotify:10421): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", quite a few times.
Can't install from flatpak back again as the .deb packages which flatpak refers to have been removed from https://repository-origin.spotify.com/pool/non-free/s/spotify-client/
