Likewise, playing Queen music on the organ is entertainment, not an art because it doesn't change lives.
It may have been an art when Queen originally performed it, but in the case of performing it on the organ today, it would be a mere imitation, a copy, a replica.
Sure, famous rock music can get you throngs of people to listen to your playing (if that is what you want) but you have to be honest to yourself of what your goal is.
A copy isn't worth much. Art is worth a lot.
