While many genres of music like rap and heavy metal feature violent content, dubstep has a violent form. The music itself is designed to synthesize violence; the more violent the sound, the better the song. Skrillex, real name Sonny Moore, is a hardcore-band-frontman-turned-dubstep-producer. His transformation from "traditional" hardcore music to hardcore electronic music is emblematic of dubstep's rise to popularity in America in the past couple years. While teens of the 90s listened to bands like Rage Against the Machine, teenage fans of dubstep are the new generation of hardcore-music listeners.
Skrillex's songs, which include the above "Scary Monsters and Nice Sprites" as well as others like "Fucking Die 1" and "Kill Everybody," juxtapose beautiful melodic samples with violent intense bass, using sampled vocals (which often become the titles of the songs) to set the tone for the "drop," the moment in the song where the heavy bass begins.
Though some violent music does inspire violence among it's listeners (i.e. mosh-pits,) dubstep's listeners often interpret the violence in the music as tongue-in-cheek. The music often features very upbeat (and even humorous) breaks between the drops, and most fans reference the violence of the music with large smiles on their faces. Dubstep has become a sort of guilty pleasure for those seeking high-energy stress release. Browsing youtube comments of dubstep videos perhaps demonstrates the light-hearted violent thoughts the songs seem to inspire. I've attached some of my favorite quotes below, as well as some further listening...
"This is dirtier than being stuck in a sperm bank for 2 weeks, with nothing to drink"
"so my mom just told me to lower the volume.. I BACK HANDED THAT BITCH!"
"When that drop hit, Batman suddenly burst through my window and punched my cat in the face.
