Some people were baffled by Donald Trump’s choice of music during his Tuesday announcement that he would seek the Republican presidential nomination for the 2016 election.

Immediately before the business magnate and reality TV star publicly acknowledged his bid, Neil Young’s 1989 hit “Rockin’ in the Free World” began to play. But Young’s manager, Elliot Roberts, told TIME in a statement that Trump was “not authorized” to use it. Going further, Roberts admitted that Young is in fact on the opposite side of the political spectrum: “Neil Young, a Canadian citizen, is a supporter of Bernie Sanders for President of the United States of America.”

Young joins a long list of musicians who have publicly opposed political candidates using their music if their views don’t quite mesh, including John Mellencamp, Foo Fighters and Tom Petty.
