What’s the difference between the Arts & Humanities and the Entertainment & Music sections?

Comics & Animation, Magazines, Movies, Music, Radio, and Television are in the Entertainment & Music section.

Books & Authors, Dancing, Performing Arts, Poetry, Theater & Acting, and Visual Arts are in the Arts & Humanities section.

All of these categories could arguably fall under Art, and they are all meant to be Entertainment. I’m not sure what’s dividing them.
