youtube views, spotify plays, album sales, single sales, whatever metric you want to use - Taylor Swift is far more successful than Kanye West has been. sorry but its just the cold hard truth. I dont understand, what is so hard to get about a mainstream soft-edged pop singer being more popular than someone who is more niche than that? it doesnt say who's better, i'm not trying to invalidate kanye. I'm just saying that Taylor Swift had bigger hits than Kanye which is what you were originally arguing about.
end of debate. in fact there was no debate in the first place, financial statistics speak for themselves.
