The AI gods have made this quite possible for coding nOObs such as myself. I wrote up a python script to copy the playlists to plex. I also set song ratings.
Now I’m working on a script that compares song ratings in plex compared to my playlist files (eg my file of 5 star songs). It will produce a deltas file for me.
Cool stuff. Will try to post on github etc when I’m happy with it all.
