adding tracks from a disk image to itunes

I am getting:

and am wondering why…

set theFolderList to {"music1", "music2", "music3", "music4"}
set thisFolder to 0
tell application "Finder"
	repeat (count theFolderList) times
		set thisFolder to thisFolder + 1
		set theLocation to "mydmg:music:" & (item thisFolder of theFolderList)
		set theMusic to get every file of folder theLocation
		
		tell application "iTunes"
			set thisSong to 0
			repeat (count theMusic) times
				set thisSong to thisSong + 1
				add item thisSong of theMusic to library playlist 1
			end repeat
		end tell
	end repeat
end tell

Thank you!

The problem is with the Finder. By default, it returns objects that other applications don’t understand (instead of the usual alias). You can use as alias list in the Finder to get the desired results; However, there is currently a bug with that when getting an alias with only one item.

Try something like this:

set theFolderList to {"music1", "music2", "music3", "music4"}

repeat with thisFolder in theFolderList
	tell application "Finder"
		try
			set theMusic to every file of folder "mydmg:music:" & (item thisFolder of theFolderList) as alias list
		on error
			-- Workaround for a bug where `alias list` doesn't return a list when there is only one item
			set theMusic to every file of folder "mydmg:music:" & (item thisFolder of theFolderList) as alias as list
		end try
	end tell
	
	tell application "iTunes"
		count theMusic
		repeat with i from 1 to result
			add (item i of theMusic) to library playlist 1
		end repeat
	end tell
end repeat

Ah, ok… Thank you very much Bruce.

Curious, is there a benefit to doing the repeats the way you did them vs. how I did originally?

the “thisFolder in theFolderList”, and the “1 to the result”?
