I think there should be "An Infinite Literature Contest", where the contestants would submit a formal grammar and the texts in the language would be judged for literary and other qualities.

Not sure why you were downvoted, it is super interesting. I know nothing of songwriting but it seems like that could be read by a singing performer in similarly to how sheet music is read by an instrument performer. In the graph, there's additional information than just the words that a singer would need to perform the song accurately.

/re-iterate i know almost nothing of music except what i like which i've been informed over and over is incorrect hah.
