Former President Donald Trump’s penchant for playing popular music at his rallies has frustrated artists who don’t appreciate his politics or his use of their work to pump up his crowds.

Different artists and musical groups have objected to the Trump campaign using their music for different reasons, ranging from political disagreements to displeasure that his campaign didn’t explicitly ask them for permission to use their work. However, the complaints are usually in vain, as blanket licenses that can be purchased by Trump’s campaign allow the use of songs regardless of the artists’ feelings.
