A quick google search shows tom petty has sold 80 million records and Britney Spears 100 million. I think you are mis-gauging what happens to music over the course of decades. Bubble gum pop and similarly positioned types of hip-hop etc do very well when they are in fashion, but don’t earn as much consistently over the long haul. Dylan’s catalogue could plausibly still earn 50 years from now.
