BlackHatDevX/openspot-music-app ? reverse-engineered prompt

Build me an OpenSpot Music app that lets people search for songs, albums, artists, and public playlists, then stream or download tracks for offline listening with no login and no ads.

I want it to work on mobile and desktop, with one app for Android and iPhone and another for Windows, Mac, and Linux. Keep the UI clean and modern, with dark mode, light mode, and a simple mini player. Users should be able to like songs, make their own playlists, import music from a public Spotify playlist link, and see trending tracks for their country. Make playback smooth, support background play, and include lock screen or headset controls where possible.

If you need to look up current docs or best practices for Expo, Tauri, or any APIs, go ahead. Please set it up so the main flows feel polished and ready to use.
