From a Wall Street Journal story by Alyssa Lukpat headlined “Musicians Bristle at Campaigns Using Their Songs”:

Music can jazz up a political campaign—until the artist wants out.

GOP presidential hopeful Vivek Ramaswamy courted trouble with the rapper Eminem when he spit an offbeat rendition of “Lose Yourself” in Iowa last month. Like other outraged musicians, Eminem through his representatives sent the campaign a cease-and-desist letter.

Candidates have a long tradition of playing songs at events in an attempt to look cool or to offer hints about their approach or platform. Artists, however, don’t always want to be pulled into campaigns—especially when their politics don’t align. The result can be embarrassing or even lead to a legal spat.
