Controlling airport express speakers other than with iTunes

[MrSmith]

Is there a way to control my Express-connected speakers other than using the pop-up at the bottom of iTunes? A menu bar app or even a widget?

Yep. Airfoil

Thanks a lot. Works like a charm. Wish there was a simple menu bar slider, though.
