playlists changed after minim refresh

[simbun]

Some time ago I moved my dad away from Sonos and set him up with MinimServer and BubbleUPnP. About 6 months later he asked if he could access his playlists from other devices, I found out that he'd created over 100 playlists in BubbleUPnP so I converted them to static m3u8 playlists and stored them on MinimServer. He still creates them in BubbleUPnP and every so often we export them, convert them and load them into MinimServer.

The script runs on Ubuntu under WSL so I have no idea if it'll run on mac OS. If you're competent on the command line you may be able to make use of it.
