UPDATED: I Hate That iTunes Done Chime! v2.0
OK. I suppose I don't actually hate it. But you might find it convenient to change the "done" chime that sounds whenever you import or convert files in iTunes. I Hate That iTunes Done Chime! v2.0 will let you select a new sound to replace "boodely-OOP!" -- which is actually named "complete.aif". You can choose from any of the default system sounds (ping, sosumi, submarine, and so on), no sound, or your own AIFF sound file.
This latest version is simply a maintenance release and is saved as universal binary.
