Your definition of art is not in agreement with any artist’s interpretation I’ve ever heard. It’s like saying a movie based on a book is not art , it just distracts from the book.

> music videos are not art.

Yes, they definitely are. I mean not all, but they can be. Just like cover photos on an LP or the music itself.

It might not do anything to you, but it's definitely art that can compliment the video. Might make it worse, might make it better. Might change the feeling.

I think it's the same situation and direction with human dancers on every pop-music stage. They add nothing to the music so why are they there? It used to be that musicians focused on great playing and singers on great singing, but now every pop-star and also rap-star must have their dancers on stage. I personally don't get it but seems like many people like it more if there are more dancers.

I'm sure some people said the same about ballet.
