Unlike the elist western art music that was focused on achieving perfection and the most profound emotions that can be experienced the music afterwards was the very opposite, it was about doing the least amount of effort, improvising, being as vulgar and transgressive as possible. Then afterwards you even have outright satanists in rock and metal. The same can be said about all other media, do you think it's influenced by the devil or it's just the devolution of human nature?
