They didn't play 80s music 30 years ago because it was the 80s...
(Actually 98 *was* playing '80s music 30 years ago.)
Now that I'm done being a smartass, I'll say it's still astounding that after two decades of radio message boards-- some folks remain convinced these once-hugely relevant stations exist purely to be their own "personal Pandora."
Fred Leonard nails it. To add, most Americans' hit-music "vocabulary" stops growing around the time they turn 30. And it's already slowed down by about 25. Please notice the hedge word "most." For a man, take the year of his high school graduation. Subtract ten. Note the year, then add 15. There you go. For the rest of his life, chances are the base of his hit-music comfort zone will consists of records from that 15-year window. (For a woman subtract six, then add 18.)
The grass is always greener. It's funny hearing a WOGL listener/complainer making the KRTH comparison. I frequently heard folks from L.A. whine about the station's insanely-tight 250-song playlist, and yearn for Oldies 98. Both seems to continue doing well for the company.
It's my understanding WOGL indeed *is* playing some of the artists Rainman listed, particularly Whitney Houston and Jeffrey Osbourne. Not so much with the others. And that's simply because Houston and Osbourne test well with the same audience that likes hearing Motown's dozen biggest hits and "Brown Eyed Girl" every four hours. Oran "Juice" Jones? Fewer than 1% of WOGL's audience would even recognize the name. And "The Rain"-- while a decent song-- was not a big Top-40 radio hit in Philadelphia. On Power 99FM and perhaps WDAS-FM sure. But not that much on WCAU-FM and certainly not Z/Electric/Eagle 106. Guess what? "The Rain" has found a home on Radio One's 100.3, which *is* playing the artists on that list. And it's a station listened largely by that underserved audience here that did grow up with Power 99FM and WDAS-FM. Makes total sense. I imagine 100.3 is also playing Cameo (at least "Candy" or "Word Up"), though admittedly I've yet to hear it. (I don't much listen to the remnants of terrestrial radio.)
Rainman will likely get his wish with regard to WOGL as Boomers continue to age out of the station's target. Then he'll be able to hear Harvey Holiday talk up "We Don't Have To Take Our Clothes Off."
