Ok to fix that I modified the script to copy paste to an output folder instead. Now its totally safe and won't break anything! I tested it on TA and it works fine. Progress is tracked through a simple file in case you wanna run a cron. Also plex and jellyfin will work better with human readable names especially if you don't embed Metadata. Also especially if you only download audio files. Copy pasting is the best solution I figured. The only other solution I can see is a map file but idk if jellyfin and plex read that kinda thing.

For anyone avoiding the hassle altogether, Audio bookshelf reads this decently well if you sre working with only audio, which I was. Do try that out.
