I don’t know if he went worldwide or if he’s just a British thing, but Lewis Capaldi is the worst offender for this in my mind. There was about 3 months where Somebody You Loved wasn’t being played by at least 2 stations at a time. 2 or 3 times an hour, every hour, every station, every day.
It was a great song the first 5 times. The next 5000 not so much.
I don’t know anything about specifics, or actual explanations, but I once heard it said that Art decorates space and music decorates time.
