GOP's only-runner Donald Trump is a big fan of Rolling Stones music and the fellas aren't happy about it. The band has warned the candidate to stop using the Stones' music at his campaign events.

During his latest victory speech Trump again blasted a Stones song over the loudspeakers, this time the 1981 hit Start Me Up. "The Rolling Stones have never given permission to the Trump campaign to use their songs and have requested that they cease all use immediately," said a Stones statement.

A Trump spokeswoman didn't immediately respond with a comment nor reveal whether the campaign had a license to play the Stones' songs, Associated Press reported.

Trump has featured Stones music for months at his campaign events, including You Can't Always Get What You Want.

Other artists on The Donald's campaign playlist — such as Adele, Elton John, Aerosmith and Neil Young — have also asked Trump 2016 to stop using their songs.

"Donald Trump was not authorised to use Rockin' in the Free World in his presidential candidacy announcement," said Young's long-time agent Elliot Roberts. "Neil Young, a Canadian citizen, is a supporter of Bernie Sanders for president of the United States of America."

The Stones are not Trump fans. "Can you imagine President Trump? The worst nightmare," guitarist Keith Richards told Billboard late in 2015. "It could happen. This is one of the wonders of this country. Who would've thought Ronald Reagan could be president?"

They don't seem to be the Republican type in any case. In 2012 Mick Jagger performed his Presidential Election Blues on Saturday Night Live slamming former Republican presidential candidate Mitt Romney.

Political campaigns don't need artists' permission to play their songs as long as the political organisation has obtained a blanket license from the performing rights organisations ASCAP and BMI for all the music in the licensing group's repertoire, notes AP. But BMI does allow songwriters and music publishers to object to their use and exclude songs from the blanket approval.
