I have an unhealthy fascination with politicians using music without permission/consent and then getting a PR headache when the artist calmly sues, publicly denounces the use, or both.
A couple of weeks ago, Donald Trump came to the Republican National Convention stage to “We are the Champions” by Queen. The band quickly told the candidate off and stopped him from using their music. Vox explains it all in a great video. I fully expect many artists will start banning certain politicians from using their music.
