Import contents of specific folder into iTunes using Applescript - applescript

Question

I have created an Applescript that will, with one click, add the contents of a specific folder on my hard drive to iTunes (I really want to avoid using the iTunes organisational system).
Applescript
tell application "iTunes"
set theFolder to ("Macintosh HD:Temp to be Listened to:Temp on iPod:")
set with_subfolders to true --list subfolders or not (recursion)
set parent_folder to theFolder
end tell
tell application "System Events"
set item_list to parent_folder
end tell
tell application "iTunes"
add contents of parent_folder to user playlist "Temp on iPod"
end tell
However, it only imports into iTunes the files from the top level/parent folder.
I want to include files from the folders in the parent folder.
Is there a way I can get it to be recursive?

Answer 1

You do not need to get all files from a folder, since iTunes does this automatically and recursively from a folder.
Just add the parent folder, like this:
set parent_folder to "Macintosh HD:Temp to be Listened to:Temp on iPod:" as alias
tell application "iTunes"
add parent_folder to user playlist "Temp on iPod"
end tell

Answer 2

Solution #1: Using entire contents of the Finder - not very fast
set theFolder to "Macintosh HD:Temp to be Listened to:Temp on iPod:"
tell application "Finder" to set filesToAdd to files of entire contents of folder theFolder as alias list
tell application "iTunes" to add filesToAdd to user playlist "Temp on iPod"
Solution #2 : Using Spotlight - very fast, but the volume must be indexed.
set theFolder to "/Temp to be Listened to/Temp on iPod"
set fileList to paragraphs of (do shell script "mdfind -onlyin " & quoted form of theFolder & space & quoted form of "kMDItemContentTypeTree == '*public.audio*'")
set filesToAdd to {}
repeat with aFile in fileList
set end of filesToAdd to POSIX file aFile as alias
end repeat
tell application "iTunes" to add filesToAdd to user playlist "Temp on iPod"
