AhamedEstiak/BlackHole-Music-app — reverse-engineered prompt

I want a clean open source music player app built from this project that feels polished and ready to use on Android first, and ideally also works on iPhone, desktop, and tablet layouts since the repo looks cross platform.

The app should let people search songs, albums, artists, and playlists, play music online or from local files, download tracks for offline listening, and keep favorites, queue, history, lyrics, sleep timer, equalizer, and playlist support. Please include playlist import from Spotify and YouTube, playlist export and backup restore, recommendations, trending music, radio style artist or genre playback, and support for multiple languages. I also want dark mode, theme colors, good portrait and landscape layouts, caching, and a simple ad free experience.

Please use what is already in the repo, fill in anything missing, fix broken parts, and make sure it actually runs. If something is outdated, look up current docs online and update it. I’d love a final result that can be launched locally with clear setup steps.
