Stations like WOGL test their music with "panels" of actual listeners. Not only are the songs they play tested, but also included are songs they might play if they got a high approval rating.
So, at any given time we have to assume that they are playing all the well performing songs within their target audience and that there are no others that they can include. And things do not change so rapidly that 5 or 6 months will make much of a difference in music test results for a station that plays no currents or recurrents.
David: I'm so glad you're here. Your expertise and experience is so helpful and grounding--especially when some of us (myself included) find our ideas kinda floating outside of reality. haha.
There was quite a bit of hubbub (including from me) before WOGL finally "came forward in time" that they were dragging their feet, possibly in spite of the research. Another way to say it: It seemed like they held onto the '70s and only early '80s for way too long when Classic Hits as a format had long since begun dropping '70s (with exceptions, of course) and had even started playing some titles from the early '90s. They obviously had reasons to resist coming forward but I wonder, do you agree with that hubbub? Do you think WOGL took quite a while longer than one would expect?
