Why play the '60s and '70s against each other? Why not play music from both decades? They were both great decades for music! I'm not sure why "oldies" stations were loath to play anything after about 1975, but that may have been their downfall. The definition of what was considered "oldies" wasn't "fluid" enough. So it fell to stations playing "classic hits" to play stuff from the later '70s, and the '80s.
The only "oldies" station we have left here in the Nashville area is 101.7 WKOM in Columbia, and they seem to use the terms "oldies" and "classic hits" somewhat interchangeably. They are a syndicated, voice-tracked station. I don't believe you would otherwise be able to find a station so well programmed in a small town like Columbia. They seem to play mid '60s to about mid '80s. That was my time frame! 8)
