Why isn't the music industry bankrupting his campaign like he was some grandma whose grandkids downloaded a song from Napster while they were visiting?
FS already responded but I’d like to add: a lot of artists condemn his campaign's use of music but sometimes it's not their choice. The rights can be held by a publisher/record label etc.
Still, the slow speed of courts is a bigger factor.
Probably because almost all popular music is owned by 2 or 3 companies and just about everyone in charge of those play golf with Trump or someone who plays with him.
