Prince died in April of 2016 and I suspect he never had a chance to forbid anything personally of Trump. Pavrotti died in 2007 way before Trump even ran for anything so I don’ t see how he personally could have forbidden Trump to use his music. Marshburn used Rihanna’s music not Trump, so how it got related to POTUS doesn’t logically follow.
I saw in another article that it was "the estate of Prince" that complained (after taking the money, of course). I'm sure it's that same with the others.
