Clochette for Mac

From David Convent:

Clochette is a very easy to use application that allows you to rename the files (on the file system) that correspond to selected tracks in iTunes.. in a fast and smart way.

Usage
---------
Note: Make sure that you have disabled the 'Keep iTunes Music folder organized' option in iTunes preferences (Preferences > Advanced), so that iTunes won't try to rename your files.

• In iTunes main window, select the tracks that correspond to the files you want to rename .
• In the Applescript menu (in iTunes), click the menu item labelled 'Clochette File Renamer'.
• Choose your preferred settings in the Clochette application main window. See the application contextual help for more info on tag options for building new patterns.
• Click the 'Rename Files' button in the Clochette main window.
• Quit Clochette or go back to iTunes.
