Kids, before you had your newfangled iPods, and even before CDs, in the Jurassic period, we used to carry huge 25-pound portable radios around on our shoulders.
They took 12 D-size batteries, which powered them for about 2 hours, and we all went deaf immediately because we had 8-inch subwoofers on either side of our left ear all day.
I'm not even kidding.
