A producer on first lady Melania Trump’s $75 million, critically panned documentary “Melania” has revealed which major music artists refused to allow their songs to appear in the film.

Guns N’ Roses, Grace Jones and the estate of Prince all rejected requests for their music to be used in the movie, longtime Trump adviser Marc Beckman told Variety in a lengthy interview published on Monday.

According to Beckman, the “guys from Guns N’ Roses split down the middle politically,” with one giving permission and the other declining.

“We needed everybody’s approval to get it in the film,” he said. “So Guns N’ Roses was definitely a disappointment for us; we all have a lot of respect for Guns N’ Roses.”

Grace Jones, meanwhile, “apparently couldn’t get over the political hurdle, notwithstanding the fact that the film is not a political film,” he claimed. “So that was disappointing, too. It’s disappointing when people put politics so far ahead, and that happened a little bit with the film, for sure.”

A lawyer for the estate of Prince, meanwhile, nixed approval even though the rights holders had granted it.

“Literally we were ready to go, and this lawyer that manages the estate was like, ‘Prince would never want his song associated with Donald Trump,’” he recalled. “And we’re like, ‘But it’s not a Donald Trump film! He comes into the movie once in a while, but this is all about Melania. It’s not political.’ And that guy blocked it. It’s so ridiculous.”

Songs by Michael Jackson, Tears for Fears, Aretha Franklin and The Rolling Stones were approved for the film.

The interview comes amid an ongoing dispute with Radiohead’s Jonny Greenwood over the use of orchestral music originally composed for “The Phantom Thread” appearing in the documentary, and President Donald Trump’s settling of a lawsuit with the estate of the late Isaac Hayes over unauthorized use of his song “Hold On, I’m Coming” throughout his campaign.
