Even though you already know the answer, I'll tell you what happened. It has turned into Pop music....and not in a good way.
There was a time where Pop / Urban music could share the charts with Dance music (I won't use the fake 3 initials like most), and the format was still pure for the most part. It wasn't compromised, and the credibility wasn't lost. You had actual Dance artists and producers making music for the clubs, and there was no need to collaborate with Disney singers to gain the approval of sheep. Those days are gone, and yes we still have the underground....but that influence is very small in comparison to the brainwashing occurring with this festival trend.
I am going to attempt to avoid names, but look at some of the stars today of the genre. A good amount of them were unknown to the mainstream world 5-10 years ago. However they were making noise in the clubs, and were very influential in their homeland overseas. But over time, they decided they wanted a piece of the USA action. They let the major labels dictate their music direction, and we started seeing these cheesy Non Dance singers all of the sudden trying to get under the umbrella and do collabs. The format does not mean anything anymore. Since Pop music has shifted to a slower, more urban direction.....you have these so called Dance producers also trying to stay relevant to the masses. They have totally forgotten their roots, and have no interest in appealing to Dance fans. They have thousands of new fans that they have sold out to.
It was expressed on this board a few years ago, that we should embrace this crossing over idea. The argument was that we had to educate non dance people about our world, by throwing them some mainstream bait paired up with a club producer. Well it looks like you folks were wrong once again, as it has backfired and created a heap of disposable crap. Even many of former Dance DJs (they have now turned into Top40 puppets) have caught this bug. They have to please their corporate mixshows, so they play the game of supporting major label's awful priorities in exchange for promotional goods and fake nominations at these annual DJ conventions. Payola at its finest, as this results in more spins for an undeserving artist and creating higher chart positions. Perhaps I'm rambling, but point is.....it was way less crooked before the genre was on their radar.
