-- some applescript fragments to manage playlists based on album art

-- NOT MEANT TO BE RUN AS IS. read below and paste what you want in script editor and run that.
-- next line intentionally there to keep you from running this accidentally.

-- this fragment will go through your Library and put every track into either 'art' or 'noart' playlist.
-- caveats:
--     you'll want to have the playlists 'art' and 'noart' already created.
--     it's really slow. youll probably want to make a few playlists out of your Library and run the script on those individually.
--     it's not always accurate. it puts some tracks that have artwork into noart.

tell application "iTunes"
	repeat with a in every track of playlist "Library"
		try
			set z to artwork 1 of a
			add (get location of a) to (playlist "art")
		on error
		        add (get location of a) to (playlist "noart")
		end try
	end repeat
end tell

-- this fragment goes through the noart playlist and moves anything it finds with art to the art playlist.
-- this way you can add artwork to stuff and clear those tracks out.

set i to 0
tell application "iTunes"
	repeat with a from (count of every track of playlist "noart") to 1 by -1
		try
			set b to artwork 1 of (track a of playlist "noart")
			add (get location of track a of playlist "noart") to (playlist "art")
			delete track (name of track a of playlist "noart") in (playlist "noart")
                        set i to (i + 1)
		end try
	end repeat
end tell
