RetroMusicPlayer/RetroMusicPlayer — reverse-engineered prompt

Build me a polished Android music player for people who listen to music stored on their phone, not streaming or downloading. I want it to feel modern and clean with a strong Material You look, dynamic colors on newer Android versions, and the three main themes of white, dark, and true black.

The app should let people browse their library by songs, albums, artists, playlists, genres, and folders. Add a nice home screen with recently played and top played music, smart playlists like recent, most played, and history, and a really good now playing screen with lots of theme options, album art, queue controls, gapless playback, lyrics with sync support, sleep timer, and easy playlist editing and reordering.

Please also include helpful everyday stuff like lock screen controls, widgets, headset and Bluetooth support, Android Auto, Chromecast, tag editing, and driving mode. Make the navigation simple and not cluttered. If anything is unclear, look up current Android guidance online and make it feel like a real finished app people would actually use.
