- Fetch musik data from /api/desa/musik/find-many endpoint
- Filter only active musik (isActive: true)
- Add search functionality by title, artist, and genre
- Implement real audio playback with HTML5 audio element
- Add play/pause, next/previous, shuffle, repeat controls
- Add progress bar with seek functionality
- Add volume control with mute toggle
- Auto-play next song when current song ends
- Add loading and empty states
- Use cover image and audio file from database
- Fix skip back/forward button handlers
