This script can be used to convert a single audio file containing multiple songs into multiple audio files.
It can be useful to split a youtube playlist.
This is just a script for me so I'm not going to maintain or port it to any other os but it should work.
It was tested on linux mint but should work on any os as long as you have ffmpeg installed and added to your PATH.
Please modify the script and change at least :
 - the inputFile
 - the variable containing chapter time codes
 - the names of your songs
 
 Enjoy :)

outputFolder = "outputPlaylist"
