EDM or Techno?

I am into ambient and progressive trance. These days anything soothing from trance and EDM genre is good to me.

For the most part, I agree. There are specific sub-genres that better identify music (e.g., "be-bop" in jazz; "honky tonk" in country music; "punk" in rock and roll), but there are places where it just goes way, way too far. I mean, math rock????? Sheesh, what's that? "Two Divided By Love"? "Nothin' From Nothin' Leaves Nothin'"?

I think EDM is just a lot better and a lot more inclusive title. And I also believe that the sub genres are important! As weird as the labels might get, they help better differentiate and identify certain types of music within a genre, and most people subscribe to them because they want to capture all the nuances. And this isn't just an EDM thing; it's the same in all genres ever, people just like to point out the fights in EDM more. I personally use sub genres to find more of the same sounding music. For instance, I really love melodic dubstep and future bass, among other things. If I referred to all EDM with the same name, I never would have been able to find more artists like ODESZA as opposed to those like old Skrillex. Additionally, how would you have been able to describe Skrillex's style change?
