Extension of my philosophico-poetical system to value literal rhyme over metaphor

My philosophico-poetrical system is not all my own. I built upon Valéry's remark: "To write regular verses destroys... an infinite number of fine possibilities but at the same time it suggests a multitude of distant and unexpected thoughts." The problem with pursuing the project and allowing for metaphor is that one starts with a line and searches for a line that rhymes and chooses a line with a metaphor in it which expresses common thoughts. By banning metaphor, one increases the chances of distant and unexpected thoughts figuring the rhyme. (I think the AI has cut my remark "That's not how I interpret the lyrics.")
