Press the “Spotify” button to launch the app.
The app uses a paid-for account, so you won’t get any adverts. BUT it’s the same account as used in the main room – so be careful about trying to play in here and the main room simultaneously.
When playing, the “Play” button shows the art for the playing song. Press it to pause playback.
Adjust the volume with the lefthand knob. Click it to mute / unmute the sound.
