Bjork (I think) said that electronic music has no soul cause no one bothered to put one in it. As a long time listener of mainly electronic music, I agree. Among the various genres and artists of electro music there is a ratio of computer/human input to each piece. I find the pieces were the human input is minimal, boring and dry. In a way the human in these sorts of music is the necessary ghost in the machine that makes the piece worth its salt.
I would be very impressed if a fully computer synthesized piece would actually strike a cord in humans. I'm not talking about brutal bam-bam-bam techno pieces that evoke no emotions whatsoever.
