I’ve been hearing of an iTunes Match glitch that somehow or another creates thousands of empty playlists. Here’s a script that will delete every empty playlist:
tell application “iTunes”
set y to (get index of last user playlist)
repeat with i from y to 1 by -1
set thisPlaylist to user playlist i
if special kind of thisPlaylist is none then
if not (exists track 1 of thisPlaylist) then
It may time-out because the number of actions it has to perform is so large. Just run it until the empties are gone.
