If you need a SIMPLE iTunes controller go to iTunesMenu
If you need COMPLETE CONTROL over iTunes, look no further.
You Control: Tunes 1.7.1 is the TOTAL CONTROL !!
You can now simply pull down your very own custom menu that gives you access to the iTunes controls (next, previous, volume, play/pause, stop), as well as displaying the current track, artist, and album. You can also navigate your entire iTunes music library from this menu as well so you never leave your current application.
