atishsharma/AT-Music-Player — reverse-engineered prompt

Build me a polished desktop music player called AT Music Pro that feels premium and smooth on Windows, Mac, and Linux.

I want it to handle both my local music library and YouTube playback, with yt dlp support for search and streaming. It should scan common audio files like MP3, FLAC, WAV, and OGG, show a clean library view with adjustable artwork size, and have a smart queue where I can drag songs around and keep playback state saved. Please include synced lyrics when available, plain lyrics as a fallback, Last.fm scrobbling, and a floating mini player that stays on top and can flip from album art to lyrics.

The app should look modern and animated, resize nicely, and feel especially solid on Linux too. Make sure FFmpeg and yt dlp are treated as required system tools and document setup clearly. I also want installable builds for each platform, not just a dev app. If you need details for lyrics, scrobbling, or packaging, look up the current docs online.
