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?
