The first link from pimylifeup installs raspotify, which is nothing but a systemd script to start librespot automatically on boot. librespot is the actual thing that runs in the background. It doesn't give you any UI. But you can use the spotify app on your windows, android, ios, macbook to play music. If you have a DAC connected to your RPI (usb or I2s), all that is required is to configure the device name in the file /etc/raspotify/confSo with volumio being out - the following are my options - request FMs with experience to comment on the ease of setup with the following; keeping in mind - touch screen compatibility via HDMI & currently the only requirement being Spotify connect.
