We can see the current iTunes track in the Dock in a pop up. To do this we have to tweak the Dock a little.


1. First quit iTunes if it’s open.

2. Then open a Terminal window (Finder->Applications->Utilities->Terminal).

3. Type the following:

        defaults write com.apple.dock itunes-notifications -bool TRUE;killall Dock

4. Then start iTunes and play a track. The pop-up will fades away after a few seconds.

5. To add the iTunes icon to the pop-up window, type the following into a Terminal window:

       defaults write com.apple.dock notification-always-show-image -bool TRUE;killall Dock

6. To deactivate, quit iTunes, then open a Terminal window and type the following two lines:

       defaults delete com.apple.dock itunes-notifications 

      defaults delete com.apple.dock notification-always-show-image;killall Dock


Note : This will only in Mac OS X Lion and Mountain Lion.
