Build me a simple music app that feels fast, private, and easy to use.

It should open as a clean single page app, let me play music smoothly, and work well on phones and desktop. Make it feel like an installable app, with an app icon and support for offline use if possible. I want the design to be minimal and modern, with no tracking, no sign in, and nothing that feels invasive. Keep it lightweight and responsive, and make sure it loads quickly.

If you need to look up anything current about browser audio or offline support, go ahead and check the latest docs online. Please keep the code straightforward and make the whole thing polished enough that it could be used as a real small music app right away.
