I wish, by some magic, we could project the modern-day formulas (so much more accurate with how people listen to music) to yesteryear. While “gatekeepers” like radio DJs and TV programmers colluding with record companies still have a lot of power, much of it has shifted to the hands of the people. You couldn’t track repeated listens on an album you bought years ago vs. an album you bought and only listened to once. You can do that when each “spin” is tracked on a streaming service. But, yes, trying to compare Drake’s chart records with that of the Beatles is very apples-and-oranges.
