title: System is adding unwanted items to my customized contextual menu in my app
body: <p>I have customized the contextual menu for my Cocoa application such that only certain items are visible. In spite of my customization, I found that the system adds a menu item -- "Add to iTunes as a spoken track". </p>
  
  <p>I tried removing this item from the menu but somehow, I am unable to get the control. Is there a way this item can be removed, or do I have to write an AppleScript to disable the iTunes option under Keyboard Shortcuts? I hate doing that since I will then have to restore it for the user.</p>
