The suit, which Young posted on his website, states, “The Campaign has willfully ignored Plaintiff’s telling it not to play the songs and willfully proceeded to play the songs despite a lack of license.” It goes on to explain that Young “in good conscience cannot allow his music to be used as a ‘theme song’ for a divisive, un-American campaign of ignorance and hate.”

Trump’s campaign has used various songs without the artists’ permission.
