QuizzityMC/OpenListen ? reverse-engineered prompt

Build me a simple open source music listening website that I can self host from static files. It should feel like a clean lightweight alternative to Spotify, with a nice player UI, album covers, track titles, artist names, and easy browsing by category. I want the music to come from a local music folder and the cover images from an img folder, so I can just drop in my own songs and art and update the song list in the main JavaScript file. Please make it easy to play, pause, skip, shuffle, and drag songs around in the queue or list if that makes sense. The page should look polished and work well on desktop and mobile. If you need to check current browser audio behavior or small UI details, look up the latest docs online. Keep it simple, clean, and easy for someone non technical to add new tracks later.
