On Saturday night, Madonna opened Avicii's set at Ultra by coyly asking "How many people in this crowd have seen Molly?" Deadmau5, who was also in South Beach this past weekend, didn't take too kindly to what he perceived as a shining endorsement for ecstasy use on the EDM scene (let's also remember the comment was also a not-so-clever-nor-thinly-veiled plug for her new album, "MDMA," which drops today). So, Deadmau5 took to Facebook early this morning to slam the First Lady of Pop.

"Very classy there madonna. "HUR DUR HAS ANYONE SEEN MOLLY???" such a great message for the young music lovers at ultra. quite the f'n philanthropist. but hey, at least yer HIP AND TRENDY! f*cking cant smack my head hard enough right now." Read on.

Followed by this, on an unrelated note:

Meanwhile, people on Twitter fired back:

He further elucidated in a blog post:

Now, weve taken EDM so far in the past decade, so goddamned far. It really hurts me to see rampant ADVOCATION of extreme bullshit lifestyles to a genre that spans pretty much any age gap these days.  Of course, ill always have my opinions about this or that… and yeah, its my personal choice not to do drugs, but im not on a fucking crusade to stamp out other peoples personal choices by no means. fuck being a crusader. Im not pro, or anti drug… but… ill easily let you know that im pro-responsibility.

Its just that simple… you can have an excellent standard of life providing you had a sense of responsibility to yourself, and those around you, REGARDLESS of whatever choices you make in your life… either good or bad (which is the opinion part).

I just feel like ive been kicked in the balls for a dollar. I’ve always been into electronic music, as far back as i can remember… and around the beginning, i really do remember the times the events i loved were pretty much outlawed by my city simply due to its speculated over-excessive drug use, and the media coverage that everyone loves to lap up around it. Yeah, that bummed me out… kinda made me feel like… how could something so damn interesting, artful, fun and just plain cool, be frowned upon by most….

but look at us now, allthough not completely, and never like to be completely, the dark veil has been lifted slightly and the music and good times and technology is starting to shine through more and more than “the latest breaking news about such and such a drug found only at these underground TECHNO RAVES - Tonight on fox!”

Go read the whole rant here. It's worth your time. He brings up some valid points. Kids losing their minds on molly at shows and festivals is absolutely a growing problem for the EDM scene as it continues to surge in popularity. A lot of people who have been in the EDM scene for a long time have compared the rampant molly use at shows to smoking while pumping gas: Just one misstep and the whole thing will spontaneously combust in everyone's face. But, then again, what can someone like Deadmau5 realistically do to prevent people from partying, without being a buzzkill and totally ruining the party? In some ways, Zimmerman's Facebook beef is forcing big influencers in the scene to openly talk about drug use versus turning a blind eye.  We could perhaps be moving towards a decisive moment for EDM. Who's side are you on?
