Vkbhat3904/Synthesia — reverse-engineered prompt

Build me a simple full stack music player called Synthesia. Users should open it in the browser, see a clean home screen with a list or grid of songs, search by title or artist, click a song to play it, pause, skip, go back, change volume, seek in the song, and see the currently playing track with basic details.

Include a small backend so the app can serve or manage the music data, and a frontend that feels polished and responsive on desktop and phone. Use sample songs or clearly marked demo data if real uploads are not set up. Keep it easy to run locally, with clear setup steps and sensible error handling when there are no songs or audio fails.

Look up current docs online if you need to. Please make the code clean enough that I can add real music files later.
