Everything you said in that first paragraph only reinforces my point, that's exactly what i'm saying. "I wouldn't say anyone can pick up a guitar and play." Well I wouldn't say anybody can run a computer program and make music. There are only a very few truly talented electronic producers out there and they are NOT making money off of other people's music. And most artists only make remixes for fun, and some of them happen to get popular. Very few of them are making any money off of them.
Replace the word "real instrument" with "computer program" and what you said is no less true. The REAL electronic artists, don't just get up on stage and press play, they mix the song live using sounds they have created.
