Something that comes up often in art that's about artists is that you'll be told that this character made an amazing, record-shattering, highly acclaimed book or movie or song or whatever and then you'll see the piece of art they made and it's painfully mid. Like, you have to accept that within the world of the story being told, that's the most amazing piece of art ever but you're sitting there like, "There's no way that would ever catch on like that IRL."
Anyway, shout out to KPop Demon Hunters for sidestepping that problem entirely by having the in universe songs chart so high IRL that they beat out actual established KPop groups, proving definitively that those songs WOULD have set the charts on fire and beat out their competition even as the new kids on the block.
