This is a question I had to ask myself when I was watching a few movie trailers not too long ago. My hypothesis: Dubstep is becoming mainstream! Every shout for joy and celebration! Dubstep is being used more with mainstream media!
... now that you're done, I'd like to explain myself, prefaced with, I am a dubstep fan. It might not seem like music, but I can assure you that because of this comic, I'm on a mission to get people to understand.
The problem is that it is true that there's different types of dubstep, and some people haven't experienced something they enjoy about it in order to accept there is "good dubstep." Check out this movie trailer for a popular movie, which features Seven Nation Army dubstep by a prominent figurehead in dubstep and electronic music, The Glitch Mob.
It's nice to see upcoming styles of music, especially during my generation. People of their 40's or 50's hold onto classic rock so heavily (as well as my generation ;P) because that's what they grew up with. Rock operas were written, people started to flood concert halls and go crazy, and they hold on to that. Sure, I might prefer a little bit of The Who every once in a while, but upcoming music should be supported. The current age will hold on to something. What are you going to hold on to?
Have a musical day! :D
