I may not understand dubstep well (or electronic music, in general, for that matter), but I respect any genre of music that has a popular following.
Here is my assessment of dubstep as I understand it. Low musicality, high bass, high volume, fixed rhythms, formulaic, great for parties, dance clubs, music videos, commercially-booming, requires a discerning ear for electronic timbres, never in my top 5 music genres (x.x). By low musicality, the average dubstep tune doesn't have the tonal complexity of, say, a piece of classical music, not necessarily masterpieces either. Passable dubstep tunes could have no more than 1 chord progression as the entire song.
Basically, with me personally, bump dubstep in the car or at the club, but keep it away from my headphones.
So, here's my hypothesis: If you take a dubstep track and overlay an electronic music track that is intricate, sophisticated and interesting, then the track would improve every time. Then, send it back to the dubstep think tank for their comments. Does it still qualify as dubstep? Are there too many notes (lul)? I don't know.
This is just an idea I've had. A friend of mine is currently learning how to DJ and his knowledge in these areas far surpasses my own.
