I agree with your definition of "poetry". It should be the category where sound dominates, that is, texts where meter, rhyme, alliteration and whatever else is used to keep the reader's attention.
The problem with a lot of poetry, and this includes even metrical, non-free verse, poetry, is that it is "not meaningful" which makes it usually "not interesting".
