Pretty much every genre changes significantly over its lifetime though. It seems like you could just say you like early dubstep just like people say, "I like old school hip hop" all the time.
I get what you’re saying but the sound is so completely different it’s not a simple evolution of style.
Listen to dnb from two decades ago you can still see where current stuff comes from. Compare early Digital Mystikz stuff with Skrillex and you wouldn’t call them the same thing.
