Earlier today, Grimes played a Boiler Room DJ set in Ibiza at the house party of pioneering techno artist Richie Hawtin. Before the set she tweeted, “Pissing off all Djs by playing t swift on boiler room tune in!” and she did just that, but not only did she play Taylor Swift, she also included Venga Boys, Daddy Yankee, and Mariah Carey’s “All I Want For Christmas is You.”

If you’ve followed Grimes over the years, you know she’s got an affinity for mainstream pop music—she once called Psy a genius—and a deeply seeded appreciation for Mariah Carey. Still, playing this type of music at a Boiler Room set at the house of an electronic music legend seemed like a move designed to ruffle some feathers. It’s textbook trolling, especially since Grimes did this knowing that she’d piss people off. There’s nothing wrong with a little trolling, and in this scenario it was hilarious to see how people reacted, but Grimes has responded to the backlash and she insists that her Boiler Room set was not a case of trolling. If we didn’t know any better, we’d think her response was another case of trolling.
