Can someone explain the appeal of japanese pop music? I mean this in an entirely non-sarcastic way, and I'm looking for a serious answer.

It can't be the lyrics unless you know japanese... maybe it's just me but I don't find the melody appealing at all (even from a more general POV where I acknowledge the wide range of melodies from country to classical to death metal).

Is there some part more to it that goes beyond melody or lyrics? I'd say something similar about extremely hardcore death metal which is essentially just noise, but I imagine to someone who has that personality type it's almost cathartic, so even that I can understand the appeal, but not japanese pop music, especially while coding lol
