If you're a baby boomer like I am, you probably grew up listening to music on the radio. More than likely, listening to music on AM Radio. These days, the kids might have a hard time grasping the concept of listening to anything, much less music, on AM. But, up until the late 60s, FM was either non-existent or played elevator music.

I first discovered music on AM about 6th grade, when our bus driver installed a speaker so that we could hear the radio on the bus. And he had it on KXOK in St. Louis. Later independent explorations of the AM dial revealed WLS in Chicago, and during my country phases, WSM in Nashville.

Also during that time, mom and dad had their station they listened to over breakfast. A station that played music, as well as passing along the news of the day. That station was KHMO.
