I quit commercial radio two years ago when I got a car with Bluetooth. I have over 6000 songs added to my Amazon prime app. All artists and albums that I want to listen to without commercial interruption.
Even on their many classic rock stations (i.e. Classic Rewind; Deep Tracks; Underground Garage) I am constantly discovering music from that era that I missed. Just some recent examples are these songs that I never heard at the time they were released:
"Willin'" by Linda Ronstadt
"As The Years Go By" by Mashmakhan
"Home and Dry" by Gerry Rafferty
So continue to expand your horizons. I even discover great rock tracks on stations that play more recent music like "The Loft", "Lithium" and "Spectrum". Then there's some great country/rock stations like "Willie's Roadhouse" and "Outlaw Country".
The classic stuff you already know is likely great but there's a lifetime of discovery still out there.
As for the original poster, it's time to move away from terrestrial radio with their narrow playlists and 22 minutes an hour (or more) of commercials.
