✅ Music player - play/pause, next/previous, seek ✅ Playback controls - shuffle, repeat (off/all/one) ✅ Progress bar - seek to any position ✅ Volume control - slider + mute button ✅ Track info - title, artist, album art ✅ Queue management - view queue, skip to track, remove ✅ Time formatting - MM:SS display ✅ Auto-advance - next track when current ends
W następnym ćwiczeniu dodamy playlists i library!
Do zobaczenia! 🚀
