flashcaliphamp/spotify-free-music ? reverse-engineered prompt

Build me a simple desktop app for Spotify free music listening that feels fast and easy to use.

I want it to let me play music, browse playlists, see song lyrics while listening, and control playback across devices like Spotify Connect. It should also handle things like downloading tracks for offline use, keeping a queue, and making the app feel more like a polished music player than a browser page. A clean dark theme would be great, and if there are ads or interruptions, try to keep the experience smooth and focused on listening.

Make it look good, work reliably, and keep the main controls obvious so someone can just open it and start playing music right away. If you need to check current Spotify related docs or APIs while building it, feel free to look them up first.
