Of all the friendships Justin Bieber has made in the music business, none are more surprising than his latest: Mountain Goats frontman John Darnielle. Following the Biebs’ already infamous run-in with the paparazzi last week, the singer/songwriter uploaded a video today of himself performing a song entitled “Short Song for Justin Bieber and His Paparazzi.”

The track finds Darnielle surprisingly coming to the superstar’s defense, saying that, while Bieber chose this life and there are bigger problems in the world, he was still in the right. As he sings in the hook: “You don’t have to leave Justin alone, but don’t be an asshole.” Check that out above and, if you like that, check out Darnielle’s brutally honest extended interview with comedian Marc Maron over at his “WTF with Marc Maron” podcast.
