|
||||
|
||||
Sequential playlist player for macOS using Music.app.
|
||||
Monitors playback state and auto-advances to the next song.
|
||||
|
||||
Behavior:
|
||||
- Asks user once before starting: "可以开始播放吗？"
|
||||
- On song finished → auto-play next song
|
||||
- On user paused → ask "要播放下一首吗？"
|
||||
- On user not listening to anything + already agreed → auto-play next
|
||||
|
||||
Usage:
|
||||
python3 play_playlist.py ~/Music/minimax-gen/playlists/深夜放松/
|
||||
python3 play_playlist.py file1.mp3 file2.mp3 file3.mp3
|
||||
python3 play_playlist.py --playlist /tmp/playlist_plan.json
