Most talk about super-geniuses is nonsense. I have found that when stars drop out, successors are usually at hand to fill their places, and the successors are merely men who have learned by application and self-discipline to get full production from an average, normal brain.
Originality is definitely missing from EDM. There are people looking for it and exploring but I feel its so big now it is just getting milked. House music is losing all its melody as it becomes more about how dirty the drop is and how energetic it is. It loses touch with what music really is.
