I tried a few nontrivial examples and it gets them completely wrong - either missing the point entirely, or having the exact opposite of the intention. One issue is this appears to only process the lyrics of the song. But the actual audio matters a lot too in conveying emotion and meaning: the tempo, the vocal subtleties, the chords, the notes, etc. etc. This also just doesn't look very deeply into relevant background. It doesn't look for references to other songs or works, nor does it use information about the life of the author at the time they wrote it, etc. But, not to be too negative, in principle some of those things could be improved on eventually. I think it could be useful some day.
