Problem solved! As always: The user is the problem, not the
software. I am no programmer, this is my only excuse for making a dumb
mistake.

My thinking mistake was this. 

I found out that emms-cache-sync *does* work for playlists, when I call it 
again with the playlist file open and active (with the song in more than one 
playlist, I have to do it in all of them, but that’s alright, how would emms 
»know« all my playlist-files to update them). But when I closed the playlist 
file and re-opened it, it was as if I never had synced, it showed the old 
information for album title and artist.

The emms-browser keeps all the new information after closing. But of course 
this is because the browser gets the information new from file everytime, while 
the playlists NEED TO BE SAVED to file after emms-cache-sync. This was my 
stupid error! I just need to save the playlist after emms-cache-sync, and 
everything is fine.

Maybe we could add a feature that asks: Playlist has been changed, save to disk?

Excuse my slow learning, please. And thanks again for emms and all the work you 
put into it!
