Music Visualizer Support

Feature Request Concept

This definitely isn't high priority but I would love to see support for music visualizers. All the classic visualizers, like M-Labs, AVS, MilkDrop etc. are open-source these days and implemented in apps like VLC Player and Clementine. I just think it's a super fun feature that lotsa music players have. We already have the playlist view

Perhaps AnalyserNode could feed input into something something OpenGL? I'm happy to help develop GUI for it in settings but I don't quite know what it would take to implement the actual visual effects.

What are the possible drawbacks or issues with the requested changes?

The main thing is that I could imagine rendering live video like that might be resource intensive? Which would be a severe drawback. But it would only run if a user is using it, and we could set it to be possible to disable on the back-end if an admin doesn't want users directing resources towards it because of the limited resources on the server.

Music + Trippy Visuals = Oooooh pretty
