I think it's hilarious that GM sells high end SUVs to high end hipsters by playing "Eminence Front".  The irony in that is so thick it can't be cut.

I loved those ads!  I just never watched them. 

The problem with making sound, from any device, be it a guitar, keyboard, piano, drum, flute, harmonica, violin, cello, or whatever kind of real instrument is, people seem to be under the impression that that whatever you (C)opyright and post online, be it a SONG, which BTW MUSIC IS A SONG for those who don't realize you don't always need a cheesy voice singing something. 
 
My Point, today's society seems to think that it's okay to take the main riff from a keyboard players song, or guitar players song, or flute players song... ETc.....  And they make money and know they wont get sued because they know the person posting it has no money after a quick internet check out of the person online.

I did not REALIZE that.

I thought;
 
A song is a single (and often standalone) work of music intended to be sung by the human voice with distinct fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections.

IBTL!!! 
 

So much to say, yet so little time.... maybe next time...

It doesn't always have to be a song, I don't think! In the old days it was a symphony, but we got a bit lazy since!
 

Turns out that copyright holders can indeed prevent politicians from using their music. At least, if they're represented by BMI...
 

All legalities aside. If an artist makes a public statement that they don't want a candidate to use their music they've made it clear they don't support the candidate.
 
I suspect that's the goal of the artist. No court, no tom foolery, no $ sought. Just a simple statement to the world (that listens) that says "I do not support thee".
 

Then they go on a "Post-Trump" tour to raise money for themselves...
