You are aware that a lot of people dumped top 40 for album rock during that time? They didn't want to hear Donny Osmond or your all-time favorite, You Light Up My Life and wanted Skynyrd and Foreigner without the MOR and bubblegum? Same with the jocks....I had friends who were just as happy listening to the TM Stereo Rock format or the lower-key AOR presentation.
So, about 16-20% of seniors dislike pop oldies...I see.
A serious underestimation on your part. And let me guess, you researched that too.
I would say that of the demographic that originally listened to rock and roll back in the 50's and 60's, would most certainly appreciate hearing them again, today. And far, far more than 1 in 5.
You've demonstrated over the years your dislike for oldies in turn for newer songs which is fine if that's what you enjoy. I believe you are highly an exception, than the rule.
Sometimes, I genuinely feel these ridiculous conclusions are just that......stories.
