EDM?? Don't know... that's that commercial radio shit with lots of vocals... that's going nowhere.. it'll fade out of popularity, fade back in and it'll be the same shitty hoovers and plastic vocals for the 'discerning' 16 year old who just discovered XTC. As long as XTC is being made, shitty trance will have it's place... haha..
The underground is heading even further away from all that prepackaged sample pack hype shit. It's going back to it's roots..
You already have this huge revival in raw warehouse sounds, early rave. Illegal rave shit. Hardcore is even coming back as this super evil fusion of everything dark and hard that happened since 1995. Straight up techno is doing better than ever. Berlin is still Berlin, Detroit still Detroit. On the other side, people are looking for warm, pleasant sounds.. happy place music like deep house and such. Genres don't really mean that much anymore..
Overall you see that a kid with a beat on a laptop is no longer impressive. Audiences are looking for better experiences, interesting live shows, interesting hardware, interactivity, shows involving visuals, actual musicianship.. etc..
