U have a point certainly but that's not the case will all of that stuff .
certain artists like derango or Psykovsky or Electrypnose or Procs can put u in very mystical states as well..
The aggresive&anxious etc stuff is a face your inner demons kind of stuff.. Unleash all the negative vibes through hard dancing ... IMO..
So it can be certainly 'spiritual'...
I get tired of the psychotic style too, plus it has become way too generic & formulaic & uninspired..
