z-huang/innertune — reverse-engineered prompt

Build me an Android app like InnerTune, a clean Material 3 YouTube Music client that lets people search YouTube Music for songs, videos, albums, and playlists, then play them without ads and with background playback. I want login support, personalized quick picks, caching and downloads for offline listening, synced lyrics with translation, skip silence, audio normalization, and controls to change tempo and pitch. Please make it feel modern with dynamic theming and support Android Auto. If it fits, include Discord rich presence too.

I want it to feel polished and easy to use, like a real everyday music player, with a nice home screen, library, player screen, downloads area, and settings. It should work well for people who use YouTube Music in supported regions, and if access is limited it should at least make sense for users who rely on their own proxy or VPN. Look up current Android docs online if you need to.
