It took me a minute to realize that every skin on the website can actually be fully used, it’s not just a zoomed in gif when you click on them!
Pro-tip: you can scale up classic winamp skins in audacious by making sure the player is selected, and pressing Ctrl+D, which make them much easier to see and use on modern displays.
Thanks OP, beyond the few limited GitHub pages of skins I knew of nowhere to find stuff like this. You’re a gent!
