I disagree with criticisms of current art or “pop” art like pop music, popular fiction books, etc. To become broadly popular you must appeal to as many people as possible. This is a balancing act between mediocrity and edginess that pushes just the right amount of boundaries to feel “new” and “fresh” without turning off a lot of people. So by definition the most popular song in the world is going to usually be fairly…
Not that everyone who likes a song buys it, but regional sales show vast differences in sales and thus tastes for different albums.
