- Implemented a new script (yt-playlist-main.py) for downloading audio from YouTube playlists. - Added configuration file (yt-playlist-config.json) to specify playlists, save paths, and binary paths. - Integrated error handling and validation for required binaries (yt-dlp, ffmpeg, aria2c). - Included functionality to update yt-dlp automatically. - Added support for parallel downloads and cleanup of removed tracks. - Implemented renumbering of downloaded tracks based on playlist order.
