In 1993, near the end of my time at KCOU, another DJ mused, "What will Kruzin' Music (i.e. the oldies show I hosted) be like in the future? What will (oldies) be? (The band) Arcwelder?"
Over three decades later, based on what I've heard, oldies now include The Cranberries, Nirvana, Tracy Chapman's "Fast Car," "The Devil Went Down To Georgia" by The Charlie Daniels Band, and "I Can't Go For That" by Hall & Oates.
The '70s, '80s, and '90s don't usually take center stage on college radio stations these days, which isn't surprising. They aren't forgotten, however, and that reassures me.
