I mean Latin has one or 2 & Bad Bunny won his first Grammy last night in that category
I don't think there's anything inherently sinister with such a category....as long as it's not called Most popular or something (Oscars tried creating a most popular category just to avoid awarding/nominating Avengers movies in best picture lol)
I expect at least Bts & bp will get noms based on their US visibility alone & some other lesser known Asian acts
Also why doesn't kpop albums qualify for "Best Global" thingy?
