Music never gets truly widespread appeal across society let alone globally. The highest selling album of the last 25 years was 1997’s Shania Twain Come On Over at 29.6 million copies verified and 40 million claimed. Bump that to all time and you hit 1982’s Michael Jackson Thriller at 47.3m verified and 66m calmed which had both people buying multiple copies over time and multi generational appeal. https://en.wikipedia.org/wiki/List_of_best-selling_albums

Not that everyone who likes a song buys it, but regional sales show vast differences in sales and thus tastes for different albums.
