As the crow flies, I went to college only about 60 miles from where I grew up; by car it was 100 miles almost on the dot. In good traffic, it was a breezy two-hour drive, but I more frequently measured it in album running time. A filled-to-the-brim compact disc of the day boasted 74 minutes of uncompressed audio. I know, I know; Americans will do anything to avoid using the metric system. But I'd wager that if you were any kind of frequent commuter back in the days of physical media, you could probably time a frequent route down to the individual track that would play as you reached your destination. If I left my college apartment to the opening bars of «One Headlight» from the Wallflowers' «Bringing Down the Horse,» I knew I'd hear the clickity-click of the disc changer about 45 minutes from home.
