How about:

"Music CDs? Yeah, I remember those, did they come before or after 8-track?"
"empeg: how much music?!!!"
"empeg: more music than you can handle!"
"Linux, the original soundtrack..."
"empeg: If music be the food of love, this thing's a sex-machine!"

I'm sure there's some *really* good 8-track and CD analogies to be put together, but I can't think of any polite ones!
