Here's a script that you can load into the Google Chrome debug window that, when called, will copy the current playlist to the clipboard.
Simply do the following:
- Navigate (and authenticate) to Google Play Music
- Go to your desired playlist
- Open the debug window by pressing F12
- Paste the script into the console window
- Run the
getCurrentPl
method - Open Excel (or any text editor; the values are tab separated)
- Press CTRL+V or Paste command from the menu
This was tested to be working today, 4 March 2019.
