The start of the blurb at the back of the book goes like: "in this beautifully written and brilliantly reasoned book, Ayn Rand throws a light on the nature of the art...." So you can see that humility is not one of her strong points.
I do like that she tried to write a philosophical novels (although she doesn't like the term). She is very keen on plot. After reading her discussion of music, I wouldn't try to introduce the Fall to her.
I would like to just say that I view "Atlas shrugged" as an evil book. In this Southpark agree with me.
