Western Music theory is an attempt to formalize certain things about music. But it's better with proper context. Like, say, a song is not about the music theory you put in it. A good song starts with a good story--and that's another craft altogether--which you make into good lyrics. Good Lyrics combine story, language quirks and phonetics. The lyrics are a heavy ingredient that needs spacing and intonation which are good-sounding and practical to a human singer, and that needs to mesh with melody and rhythm. Then comes harmony and the doses of emotion you can put into it, and that's what this article is about. You can certainly code lots of ingredients. For example, you can use embeddings to find better rhymes faster when composing a lyrics, or even LLM help to check if your lyrics make sense (If ChatGPT can guess what your lyrics are about, a human may be able too). You can use a host of computer utilities to find harmonies, and even use voice synthesizers to sketch the singing. But at the end, what makes a piece of music interesting is how well it meshes with its listener...you can model that with statistics, if you are pedantic enough, but at that point the maws of hell open and suck your soul out.
