>>60046754answer: post grunge became the basis for an entire pop formula through the mid-90's until the early 2000s. by then they had exhausted the formula so there were 2 main directions music went into: poppier punk (like Blink 182) or darker, heavier and more aggressive (trying to appeal to the boys that are rock's economic base)
so what was a much more balanced and unified rock idiom ended up fracturing and flowing in two different directions again. it's about the early oughts I stopped listening to new radio rock - for good reason.
