I'm not sure what we're arguing about, but popular music is a generational thing.
You didn't hear Al Jolson or Glenn Miller on rock or pop stations in the 1960s or 1970s, so it's not surprising if a lot of stations don't play the Rolling Stones or the Police today.
I can still find Aerosmith and Santana on the radio. Led Zeppelin and Lynyrd Skynyrd too. And Nirvana and 25 year old Pearl Jam and Gin Blossoms and Spin Doctors.
Plenty of “old and older” music on the dial. But not from the time in between.
