President Clinton cleared his throat. "Well, I don't know about all the technical stuff, but basically what it does is it lets you sing along with the top hits of the day. And if you don't know all the lyrics, they can be provided for you. Do you have Fleetwood Mac music on your planet?"
Zoltar chuckled. "We developed Fleetwood Mac music several of your Earth centuries ago. But this device is fascinating." He turned the machine over in his spindly hands. "And in exchange for this technology, all you want is detailed specifications for anti-gravity space travel?"
"Well, that, and we would like to be able to make crop circles."
