I don't have a similarly elegant answer to your query, but it made me pause and consider why I dislike poetry and in lesser way, rap music.

I dislike poetry (and rap) because it is too introspective, too personal, too self centred and painting a picture of the author's mindset that is lost on someone else. Other art forms try to elicit an emotion to the readers or viewers. They're telling a story, presenting an idea for someone else's eyes. Feels to me like no one can appreciate the poet's art and depth more than its author. As such, there is no bad poetry, which is why it's that easy to have robots convince us that random words are instead contents of a particularly troubled mind.
