After spending so much time on my rebuttal to "Music of the Gods" by Lindsay Perigo, I want to now move on to Rand's own words. When people use Rand as a weapon to justify their own musical passions, it is necessary to quote Rand herself on the matter.
In a "Q&A" session from AYN RAND ANSWERS:
So many combinations of premises are possible that you can't make a rule applicable to everyone who claims to like all kinds of art. You can say the same about people who claim they only like "romantic" art or-be careful here-"Objectivist" art (if there ever were such a thing, which there isn't.) You cannot always be sure what a person's premises are; most people are inconsistent.
