Only on moldy oldie stations that play yesteryear's hits (and they've now scoped away from the songs of the 50s, playing 60-70s-80s).
Rock of today is unlikely to even be heard on radio these days.

Taking Chicago as an example, the most listened to radio station is WVAZ - which is ‘urban adult contemporary’. No Beatles records are played there I assure you.
