Don't mean to hijack this thread, but I built out a mini Spotify player with visualization support: https://github.com/dvx/lofi

Even had a few folks contribute a couple of neat visualizations[1] :)

PS: Visualizations were unfortunately deprecated on Macs since like 1.5.0 because of the incredible difficulty of getting the audio stream data. Pretty sure there's no way of doing it these days outside of a kext.

Actually the new Music.app will load visualization plugins on SIP disabled systems from a specific folder and specific format, although it's been far too long now for me to remember where that folder was. I'm sure some keen reversers can take a look at Music.app and figure it out again. I for one absolutely love the iTunes visualizers, they even have hidden key commands to manipulate them with.
