You're not the only one - check out https://getwacup.com/ for a more modern version. The new offering from https://winamp.com/ is - I think - going to be mobile-focussed? A new codebase entirely?

Webamp can also do Milkdrop visualizations, which is pretty crazy - eg https://webamp.org/?butterchurnPresetUrl=https%3A%2F%2Funpkg... I had a link I've since lost to one which was a shader-skin, which mirrored milkdrop back into the rest of the UI. It was pretty trippy, and wholly unexpected!

Both projects have good Discord servers, as well. :) See https://discord.gg/XuJPJEm and https://discord.gg/248Z7QA, respectively.
