What to Do

Is making music something "good and new"? Art?

Explicitly yes:

> I mean new things in a very general sense. Newton's physics was a good new thing. Indeed, the first version of this principle was to have good new ideas. But that didn't seem general enough: it didn't include making art or music, for example, except insofar as they embody new ideas.

Art should be, yes. Unfortunately a lot of visual art being produced from art schools and shown in museums / galleries are forms of criticism. The article mentions crticism as not being a good new thing. The message they seek to convey is more of a priority than the creation of a Good Thing. (In reality modern art is a mixture of varying degrees of criticism and creation)

This is partly because modern conceptual art is about concepts so it's very easy for it to be overtaken by a political or critical message as the concept.
