Presidential candidate Donald Trump has been using R.E.M.'s song "End of the World as We Know It (And I Feel Fine) out on the campaign trail and the band isn't happy about it.

On Wednesday, Trump appeared on Capitol Hill at a rally against President Obama's Iran deal and walked up to the podium as the song played.

R.E.M.'s lead singer, Michael Stipe was "livid" over the use of the song at the event.

"Go f*ck yourselves, the lot of you -- you sad, attention-grabbing, power-hungry little men," Stipe said in an email to The Daily Beast. "Do not use our music or my voice for your moronic charade of a campaign."

The band also posted on Facebook:

"While we do not authorize or condone the use of our music at this political event, and do ask that these candidates cease and desist from doing so, let us remember that there are things of greater importance at stake here," R.E.M. said.

"The media and the American voter should focus on the bigger picture, and not allow grandstanding politicians to distract us from the pressing issues of the day and of the current Presidential campaign."
