OS X 10.7.4 Quarantine Issue?
Two users have reported that after updating to Lion 10.7.4, downloaded script applets from this site would bounce in the Dock when launched and would not open. It turns out that the users had previously disabled the quarantine system. This normally alerts you when a new application or document has been downloaded from the internet as you are about to open it for the first time. For some reason this setting was not picked up in 10.7.4or somethingand logs an error like this to Console.app:
posix_spawn("path/to/the/app",...): Operation not permitted
Topher Kessler has an article at cnet (published before this 10.7.4 issue arose) that explains how the quarantine setting works and how you can reset it in order to get the downloaded apps running correctly.
UPDATED: This Tag That Tag v3.1
This Tag That Tag will assist with swapping, copying, and appending data between two user-chosen tags in selected tracks or tracks in the selected playlist:
Swap - swap data between tags, ex: ARTIST<->COMPOSER
Copy - copy data from one to another tag, ex: ARTIST->COMPOSER ARTIST
Append - append data from one tag to the end of another, ex: ARTIST->COMPOSER - ARTIST
Prepend - prepend data from one tag to the beginning of another, ex: ARTIST->ARTIST - COMPOSER
The latter three actions also provide an option to delete the info from the first tag after the copy.

This latest version allows numerical tag data to be copied (for example, the Year tag's data can be copied to the Comments tag).
UPDATED: Batch Export Playlists v1.1
Batch Export Playlists will export each selected plain, Smart, and Genius playlist as individual XML or M3U files to a user selected directory. Such files can be imported into iTunes again later.
This latest version correctly handles forward slashes in playlist names and has other minor code finesses.

UPDATED: Save Album Art as folder.jpg v2.2
Save Album Art as folder.jpg v2.2 will export the artwork of the selected tracks or tracks in the selected playlist as a JPEG image file named folder.jpg to the folder which contains each selected track's file--presumably the track's Album folder.

Many third-party music players and systems (Sonos, for example) may look for a "folder.jpg" here to use as display artwork.
This latest version is basically a maintenance update and is now a stay-open app that will float above iTunes while running.
Custom Playlist Column Views, Sorta
Here's something I'm often asked which Correspondent Rob Falk put succinctly: "Is there a way to clone a playlist view...other than the Library [using Assimilate View Options]? I frequently need to create a playlist that has a specific set of columns, that are not the same as the library, and was looking for a way to automate that."
There sorta kinda is.
My first thought was to use AppleScript to just duplicate an existing playlist that already had the requisite view settings. (The duplicate command is typically used to copy a track from one playlist to another.) Unfortunately, when iTunes' AppleScript duplicate command is used to copy a playlist itbafflinglycreates a new untitled and empty playlist using the properties and views of the Music library playlist. Same as just creating a new playlist. That doesn't seem right, does it? You'd thinkwell, I thought anywaythat using duplicate to copy a playlist would behave the same as the playlist contextual menu command "Duplicate" (control-click or right-click on the name of the playlist):

So, my next thought was...just use "Duplicate". The playlist will be perfectly duplicated, column views and all, and selected in the Source list. Now you'll have a new playlist named the same as the original with a "1" at the end and which is populated with the original's tracks (if it had any). You could create a bunch of playlists with columns set the various ways you like and then "Duplicate" them when you required one. Just rename the new duplicated playlist and delete any tracks. And that part can be automated.
The workflow, then, is to "Duplicate" a playlist manually with the contextual menu command and then run this script right afterwards:
UPDATED: Save Album Art to Album Folder v4.2
Save Album Art to Album Folder v4.2 exports the display artwork (the first artwork of a track) of the selected tracks, or the tracks in a selected playlist, to either the track's file's folder (presumably its "Album" folder) or a user-chosen locationthat is, all artwork will be exported to a single chosen folder. Various tweaks to the exported image can be made beforehand:

This latest version now floats above iTunes while running and has some minor code finesses.
