mardous/BoomingMusic — reverse-engineered prompt

Build me a modern Android music player for offline listening that feels clean, fast, and polished, with a Material You style. I want it to scan songs on the device, let me browse by songs, albums, artists, playlists, and folders, and have a really nice now playing screen with queue controls, gapless playback, replay gain, sleep timer, widgets, and Bluetooth or headset controls.

Please include synced lyrics support, including automatic lyrics download, editing, word by word timing, and translated lyrics when available. I also want a built in equalizer with multiple bands, presets, and support for importing headphone correction profiles. Add smart playlists like recently played, most played, and history, plus scrobbling to Last.fm and ListenBrainz, tag editing, automatic artist images, library include or exclude folder filtering, and Android Auto support.

Make it feel smooth and reliable, and use current Android best practices. If anything is unclear, look up the latest Android docs online.
