Car crash type beat can be described as an actual car crash in musical form. Only it's barely even musical at all. This is quite possibly the worst genre ever crafted with its primary characteristics being that it's ear piercingly loud and distorted to the point it sounds like you just got in a car crash, it uses goofy ass samples, it's bpm can range from 140 all the way to 300, and don't forget to turn your brain off entirely while making it. And you can't forget to add real car crash sounds in the song. It can't be car crash type beat without cars crashing.
