I objectively think bts, blackpink and twice. Just look at their growth in monthly listeners and followers, etc. They are garnering attention or listeners even from untapped and uncharted markets and countries.
I am still amazed on their growth in different aspects.
Sorry, I don't know a better term for GP or locals or non-fans (I hate the GP terminology). I stated conversion to casual listeners OR stan since not all listeners are converted to fans.
No bashing or fighting please. 
What do you think?
