Brostep is a
relatively new sub-genre of music (born out of Dubstep) with an emphasis on a mid-range bass sound with mutating LFO speed.
Dubstep "purists", while not happy, only have themselves to blame as they should have realized that the most accesable elements of any genre will always end up being at the center of a new subgenre.
Unforunately these people do not seem to realize that it would be in traditional dubstep's
best interest for there to be as many people making poor facsimiles of the "dubstep" genre as there are the "brostep" genre as it would be an indicator that people are actually still
interested in the style to which they dedicate their future hearing loss.
