In her introduction, she asks the crowd if anyone's seen "Molly," which within the context of an electronic dance festival (and her new album's title), likely references the street name for a pure form of the rave drug MDMA. A sly way of referencing one's self, t-shirt and all? A pure form of Madonna.
Watch Madonna's surprise appearance:
After the brief introduction, Avicii came out and Madonna stuck around to dance alongside the DJ, mouthing the words to her song. There is no doubt that the crowd absolutely lost their minds with excitement.
