Every time I set out to memorize something, be it a poem, prose, song, etc., other parts of my cognitive life tend to improve. And not just the linguistic parts -- I am able to focus while programming much more easily, for example, which for me is a non-linguistic task. Maybe it has something to do with working to increase the overall page size of my brain or something.
