Arashi used to be in the latter half, but since they're finally available on streaming services it definitely helped.
Not being on streaming services is pretty much what prevented Yonezu Kenshi from getting the 1st place. Wouldn't be surprised to see RADWIMPS a bit higher too, since you can't stream their works in Japan (but you overseas, go figure).
Queen being at number 8 shows how huge Bohemian Rapsody was lol
