I have performed a new install of the music-screen-api and have got to step 7 of the install instruction and am getting th efollowing error:

If you're connecting over SSH you'll need to add another environment variable to the command to access the display like this:

pi@raspberrypi:~ $ DISPLAY=:0 python3 music-screen-api/go_sonos_highres.py

I submitted a PR to handle this scenario a bit better.
