In most of Plato's works, particularly in The Republic, he advocates for uplifting art that propagandizes supremacy of the state. All other use of art is frivolous and dangerous, indulging individual sentiment at the expense of communal life. His basic suspicion about art is also ours, and so his discourses remain relevant. Even though we may not have a state that demands unflinching devotion and sacrifice at all times, we do have a consumer economy that desperately needs feeding by a narrow range of mostly positive consumer emotion, or at least by the desire for positive emotion. Plato would lament the lack of state today, but, if he gave in to the times he'd probably advocate for just about every art form casually accessible now.
