Donald Trump has made a habit of using unauthorized songs on his campaign trail.

Aerosmith frontman Steven Tyler threatened to sue Trump him if he didn’t stop playing the rock band’s “Dream On”; R.E.M.’s bassist tweeted “go f—k yourselves” after The Donald used “It’s the End of the World as We Know It” during a rally; and, most recently, at the Republican National Convention, he made his entrance to Queen’s “We Are the Champions” and played the Rolling Stones’ “You Can’t Always Get What You Want” after having officially been named the presidential nominee—both of which the bands made clear were used without permission.

Now, unaffected artists are taking a stand and trying to put a stop to getting Trump’d before it starts. On last night’s episode of “Last Week Tonight With John Oliver,” Usher, Dan Reynolds (of Imagine Dragons), Sheryl Crow, Cyndi Lauper, Michael Bolton, Josh Groban, and others joined forces for a new segment and performed an original tongue-in-cheek tune that urged politicians to refrain from using their music:

“Don’t use our song/ ’cause you use it wrong/ it might seem appealing/ but you’re just stealing/ don’t use our song/ it just seems wrong/ by the time this tune is through, you’ll be lucky if we don’t sue.”

Usher also mocks politicians’ go-to tactics (“Bring out your smile and backdrop of ethnically-diverse teens”) and breaks song to give it to us straight: “That’s licensing; you gotta call my publisher.”
