LUC4N3X/Levyra-deepsound ? reverse-engineered prompt

Build me a clean open source music player for Android and Windows that lets people listen to both streamed music and their own local songs in one place.

It should feel simple and beautiful, with album artwork, synced lyrics, offline downloads, and a radio style discovery experience. I want it to work without making people sign in or create an account, and it should not show ads or track users. Make the library handle both online and offline music smoothly, with a polished modern look and a focus on easy listening.

If you need to check anything, look up current docs online and then keep iterating until it feels like a real app someone would actually use every day.
