as some of you may have noticed, there are currently issues with Spotify and Archphile, as librespot fails to connect.
As a temporary workaround (thanks to pinkdot from diyaudio) you can do the following:
If librespot is enabled, then:
systemctl disable librespot
wget https://raw.githubusercontent.com/archphile/playground/master/librespot-archphile/librespot.service -O /usr/lib/systemd/system/librespot.service
Finally, you can start librespot service (and enable it if you wish).
Please note that the above procedure does not solve the problem. It just increases the possibilities of librespot to connect.
