Perhaps the Hall & Oates sweeper indicates that the station may indeed venture into the 80s musically. I'm seeing more and more of "today's oldies" stations offer songs from the mid-60s through the early 80s.
Is this good programming? Lots remain to be seen but it's not rocket science to understand the whys. I'm sure it's too attract 35+ to offset the older demos who would gravitate to the station. It's all part of the ad/revenue game.
I have concerns and let me point to 93.1 as an example of what I mean. I heard them via streaming as I live in Jacksonville, Fl. One morning I heard Connie Francis as a lost oldie feature and then a song or two later, Led Zeppelin. And this type of programming occured fairly frequently from what I heard. It's not my idea of tight programming giving a unique station sound. I'm not in the biz but saying this from a listener perspective. They were all over the place. Yeah, they were doing well but I'm not sure how that kind of programming would have fared in the long run.
The danger as I see it is this. No matter how much classic rock you may play, you will not overtake a heritage station doing the format. Why should a classic rock lover hear Motown or songs they would consider lame?
And for the core oldies-loving audience, you run the risk of sounding so much like everyone else so they wouldn't really bother.
My two cents - the format can work but I woud concentrate more with pop hits from the 70s and early 80s that will flow well next to a 60s song. It's a tall undertaking to make it work. But I think there is room on the dial to sound different and attract multiple demos.
I've often used the song "Undercover Angel" as an example to illustrate the type sound I mean. No rock station would play it. AC would play it perhaps as a request. But it's upbeat, it was a big hit and I could hear that song followed by the Supremes.
Personally, I wish the days of pure oldies could return. To me there is nothing finer that hearing mostly 60s with a little sprinkling of 70s and 1 or 2 pre Beatles songs thrown in. But as long as the ad rules exist, all we have nowadays is remembering how it was.
