An electronic genre that is where sub bass is key, do not confuse it with brostep, which is made by artists like Skrillex, that have no soul in them, and are made to make money, much like the rest of America's music.
Dubstep is different than brostep. Remember that!
American: Do you wanna go listen to that new dubstep song by Skrillex?
Dubstepper: No, let's go listen to some actual dubstep like Skream or something.
