MUD has a solution to Apple’s removal of album artwork cover in Playlists
I have previously posted about how Apple removed Album Artwork from it’s playlist creation (it used to add 4 album covers) and you have to manually add it, but this post from MUD or Make Use Of has a solution that is an improvement on the album artwork.
This is the shortcut the Playlist Cover Art Generator, which you can customize to show 4 to 47 covers and have text as well. You have to allow private scripts and large datasets, but it works fast and well.
Here is one I created for my 1971-1972 playlist.
