This is an interesting concept (AI lyric interpretation) and my comment is something a bit deeper than this concept itself.
Perhaps I'm showing my age, but what makes lyric interpretation so cool is that it's the intersection of two people's life experiences - the song writer and the listener.
There's often no single meaning of a song. It may mean one thing for the writer and something completely different for the listener.
What happens in online communities where people talk about what song lyrics mean to them is the creation of actual community. That's both interesting and impactful.
