I was asking my wife rhetorically really because of the theme music on many of the modern ones I have been watching. Now she brought up a good point which is that maybe its part of the localization. Do primarily to my eyes getting worse I now watched them dubbed (although dubbs are much better now than in the 90’s). Now previously I don’t think they really changed the music but now im not 100% sure. Anyone actually watch the japanese broadcasts and know if they localize to that degree? If not does anyone know if hip hop became popular in japan or korea or such?
Talking about Korea specifically, the hip-hop scene has been growing in popularity for a while now. I first became aware of Korean hip-hop in the late 2000’s with Epik High. In modern Kpop, one or more members specializing in rap is pretty standard with many songs featuring a rap segment.
I assume you are talking about Tower of God, a series that is adapting a Korean manhwa. Fittingly, several of the OPs and EDs are performed by a Kpop group called Stray Kids. The group has 3 rap-focused members that even perform as a trio under the name 3RACHA.
