Music evolves so does Dubstep, House,etc,...
The only thing that makes me upset is how a lot producers are focusing on blatantly copying someone else's sounds or song structures, it is funny since a lot of people seem to care more about how to emulate a sound rather than creating interesting melodies and composition, just because technology allows it to and processing power on computers increase there is no need to switch between 20 synth sounds for the sake of it.
Sadly music producers are becoming copy cats, the same thing has happened to other genres such as Drum and Bass for example (Ed Rush and Optical have been copied to death); it seems to me that if someone creates a successful sound or style by trying something different there are thousands of other people that can't be bothered to try making something original and they just copy the same formula.
I think music is for people to be creative with and to show their artistic expression and not be afraid of trying new things out, for a generation in which record labels are no longer needed and music ideas can flow freely, it is sad to see how desperate producers are by trying to emulate an style to get the same recognition as the ones they have copied from.
