The Trump campaign pays license fees to use these songs in public venues. The artists gets paid, and then wants the customer to not use the songs? I would call that fraud.
If the Prince Estate does not want the songs to be used that way, they should pony up the money and buy them back from whatever label that has authority to license them out.
Or they can shut up
