How can you evaluate a system with highly processed music?

You can’t evaluate your system’s abilities by playback of electronic and highly produced pop. I found that all my systems can recreate those genres effortlessly. My non-audiophile friends (sounds arrogant of me) always lose their minds when I play something “highly processed” as they experience that emotion that comes with hearing near perfect reproduction of music.. yes, I know that’s subjective….FWIW I’ve found that most of my listening sessions start with electronic music and that after 30 minutes or so I begin to get fatigued. It sounds fantastic initially but I think our brains aren’t suited to long listening sessions with that perfectly articulated sound. If you want to test your system (and acoustics) try a symphony or rock band. Yes, I know the list of variables is endless and subjective and open to fierce debate but these genres will reveal your systems weaknesses much faster than “highly processed” pop/electronic.

I knew I had the right system for me when I stopped listening to the equipment and concentrated on the music. I always use vocals, piano, violin, sax and cymbals to evaluate a system. Electronic music won’t show the accuracy or realism of a system IMO.

I don't know why you'd want to evaluate a system with music other than the kind that you like. Personally, I wouldn't care how music I don't listen to sounds on my system. I listen to rock and electronic, so how classical guitar sounds on my system would be meaningless to me. 

I've probably already mentioned this elsewhere, but a violin/fiddle sounds distinctly different when it's under your ear...in other words, you are playing it yourself...than it does when somebody else is playing it, even a couple feet away.

Defining what you mean by "highly processed" would be helpful when asking this question. Do you consider Queen's Bohemian Rhapsody to be highly processed? How about every Steely Dan or Rush album? One could make the argument that anything recorded on master tapes is highly processed. But let me stop with the rhetorical questions. I can listen to a Brian Eno or Richard H. Kirk or Dead Can Dance or Kraftwerk album and find as much nuance and musicality being revealed than if I listen to Abraxas

I can listen to contemporary and earlier electronic and ambient music and can find that the layered complexity can challenge the limitations of systems and also tell you if the system is revealing everything in the recording.  That has to do as much with one's ability to hear vs. listening. 

I find my system reveals more when everyone is asleep and the house is dead quiet and I'm listening on headphones vs. when the house is "alive" and I'm listening w/ my monitor speakers. 

I think the proper question would be how can you evaluate a system with a crappy recording and environmental noise influencing the listening experience.
