About this extension
🎵 YouTube Music Jam — Listen Together in Real-Time!

Ever wanted to listen to YouTube Music with your friends at the same time, like Spotify Jam? Now you can!

HOW IT WORKS:
1. One person clicks "Host Session" — gets a 6-letter code
2. Friends enter the code and click "Join"
3. That's it! You're synced. Play, pause, skip — everything stays in sync.

FEATURES:
• Real-time P2P sync — track changes, play/pause, and seek are shared instantly
• Bidirectional control — anyone in the session can change the music
• No server needed — direct peer-to-peer connection via WebRTC
• No account required — just share the code
• Free browsing — browse Home, Search, Library without affecting the session
• Dark theme UI matching YouTube Music style
• Works behind NAT — built-in TURN server fallback

PRIVACY:
• No data collection — everything stays between you and your friends
• No external servers store your data
• Direct encrypted WebRTC connection

Just open YouTube Music, click the extension icon, and start jamming together! 🎧
