I generated playlists in the past by filtering each comment keyword and then making one, but I have something like 25 playlists, and each time I make changes in the MP3s (e.g., some of them were not labeled correctly, or I want to add some more, etc.) then I have to regenerate several of them.
I thought that there might be a script that would automate things, and I found this one. But I'm not sure if I got the process right. It appears that all I have to do is to put the export file in the export folder in appdata. It's just that it's mentioned in one line not in the docs
but in a page linked by it:
Finally, I looked at the instructions, and there are six steps, but I already have keywords in the comment separated by a blank space. All I have to do is to do the export command, but it looks like the script doesn't work.
