In India there are 22 different “official” languages and more than a 100 more; Hindi is the number-one official language with English in second place. There are some 1.38 billion people in India, so even if only 24% of them spoke English it would be as many English speakers as there are in the U.S.
There are some 300 languages in China, with the main ones being Mandarin, Wu, Min and Yue. There are 1.4 billion Chinese, so it would probably be comparatively easy, numbers-wise, for a band to go quadruple platinum with a recording in Yue.
There are several theories about the dominance of English when it comes to rock. One of which is that it is fairly well accepted that rock was established in the U.S.

It was clear the former Ossis were all-in on what is arguably one of the greatest American exports of all time.
