yeah and it's a fucking stupid thing to say since _most_ dancing music -counted by hours per person per time on dancefloor- is electronic. full electronic, there's no pretense about how it was produced. ever since the rave revolution of '90s.
and then compare that to metallica. why the fuck did the author bring dancing to this at all? especially when classical concerts pretty much as a rule nowadays have __no__ dancing or even possibility for dancing - so concerts with dozens of actual instrument players have no possibility for dancing whatsoever while deadmau5, skrillex, daft punk, js16 etc concerts HAVE NO SEATING AT ALL.
so what the fuck? total fail.
if it sounds good it sounds good, don't let anything else come between you and the music - don't give a shit if it's produced by entering a program into a c64, if it's just one dude and his mouth and a loop-device, if it's a full symphonic orchestra, if it's just an 80's sequencer, a "normal" rock band, a guy with a guitar.. none of that matters - music is very easy to judge, just listen to it. music schools can teach people what sounds "right", but they can't teach people what people will enjoy, this is why music schools focus on complicated to play shit jazz nowadays... they can judge the players skills with it, too bad the playing skill of the player is just a small portion of being a good artist people want to actually listen to play.
