Remove n Characters From Front or Back v4.0 helps you delete a specified number of characters from either the beginning or the ending of the Song Name, Album, Artist, Comments, Composer or Show tag (or their "Sort" siblings) of each selected track. For example, delete the initial digits and the space from "01 First Track", "02 Second Track", and so on.
This latest version is written as a Cocoa-AppleScript Applet and can only run in OS X 10.6 or 10.7. As you can see from the pic above, it consolidates all settings into a single window and provides an example that is updated as the settings are changed. Text between the arrows would be removed.
