I am really interested in this as well. I love dimming the lights, pouring one, and setting up some good tunes. I’m just not a fan of a static Image on the screen. A visualizer, or growth for open source visualizer plug-ins, allow so much flexibility with Plex as an audio player.
Also, the static screen is an instant no-go for my OLED with potential for burn-in, so Plex on the screen doesn’t work for me as an audio player in that Use Case and currently makes me look for alternatives.
