Madonna took to the stage to introduce Avicii at Miami's Ultra Music Festival on Saturday, and asked, "How many people in this crowd have seen molly?," something that upset Deadmau5, one of the leading producers of EDM.

Just to clear things up, Molly is slang for MDMA, the active chemical in ecstasy, a drug often associated with electronic dance music (EDM) concerts.

When Deadmau5 heard Madonna's question to the crowd he sounded off on Facebook.

"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! fu**ing cant smack my head hard enough right now."

He followed that up with another message, saying "I can appriciate her meteoric career, and all good deeds done, but WHAT THE F**K WAS THAT?. That's your big contribution to EDM? Thats your big message to ultra attendies? hipsterspeak for looking for drugs? f**k off you fu**ing IDIOT."

Deadmau5 later clarified his statements, telling commentators that it's all about responsibility and not promoting drugs to a younger crowd.

Do you agree with Deadmau5?
