After my previous post, I remembered seeing an option (which I've never used, though):
in the auto-playlist edit dialog box, in the bottom left corner:
automatically export a static copy
Fox63, it's worth giving it a try, it could do the trick for you: pseudo-tag Playlist + static copies of your auto-playlists.
I've tried this before but it doesn't seem to do anything at all.
To be honest, I don't even understand what that command does.
To be clear, I'm creating classics, 100 songs for each year, and with two fields, year and position, it makes me the rankings automatically.
Just look for the ranking e.g. 1990 in the year field and sort it all with the location field.
Unfortunately a song can appear in several years, usually the next.
I had thought of comparing which classification is selected and with that take the position that the song occupies correctly.
It's probably best to use manual playlists.
I like to try :-)
Thank you anyway.
