David Crosby is not a fan of Neil Young's recent decision to allow Republican presidential nominee Donald Trump to use his song "Rockin' in the Free World" at rallies.

Young recently backed off his stance regarding Trump's use of the track, saying in a new interview that he "doesn't have anything against him" for using it.

"The fact that I said I was for Bernie Sanders and then Trump didn't ask me to use 'Rockin' in the Free World' doesn't mean that he can't use it," Young told Reuters.

"He actually got a license to use it. I mean, he said he did and I believe him. So I got nothing against him. You know, once the music goes out, everybody can use it for anything."

Crosby attacked the decision on Twitter. Responding to a fan's question asking what he thought of Young's move, Crosby said, "Everybody makes mistakes sometimes. There's one."
