metrolistgroup/metrolist — reverse-engineered prompt

Build me a polished Android music app like a free YouTube Music client. I want users to search for songs, videos, albums, artists, and playlists, stream music from YouTube Music, play in the background, and save or cache music for offline listening.

Make it feel like a real music player with a home page, artist and album pages, playlist management, a full screen player, queue editing, sleep timer, skip silence, equalizer, tempo and pitch controls, and synced lyrics with translation. Users should be able to log in to their YouTube Music account and sync their songs, artists, albums, and playlists if possible.

Please include light, dark, black, and dynamic themes with a clean Material style. Add nice extras like a home screen widget, importing playlists, recognizing music, and listening together with friends in real time. Keep it free and open source friendly. Use Kotlin for Android, and look up current Android docs online if needed.
