jpdcs/SongHub-Karaoke-PC ? reverse-engineered prompt

Build me a free offline karaoke app for PC that feels like a real karaoke machine at home.

I want to drop in my own legally owned song files, scan folders, and have the app build a searchable library with song numbers, titles, and artists. It should support MIDI, MP3, MP4, CDG with matching audio, and Chorus songs too. While singing, I need big clear lyrics with per word highlighting, a song intro screen, next song info, a reservation queue, fullscreen mode, and controls to change key, tempo, melody, and chorus on the fly.

Also include a settings area where I can create a song database, add folders, choose language or country filters, set starting numbers, and turn on duplicate filtering. It should remember my preferences, support English and Tagalog, and have a remote control style feature for other devices on the same network. If you need to check current docs for anything, look them up online.
