When I was growing up in the 1980’s there was a local “oldies” station playing rock and roll from the late 50’s early 60’s.
An equivalent today would be playing music from the late 90’s, early 2000’s. Going back down memory lane with some Britney Spears and Outkast!
Heavy Metal, Disco, Grunge, 80’s synth pop… it would all be too old for that oldies station.
