This iteration does, but that's an artifact of how it's being generated: small spectograms that mutate without emotional direction (by which I mean we expect things like chord changes and intervals in melodies that we associate with emotional expressions - elevator music also stays in the neutral zone by design).

I expect with some further work, someone could add a layer on top of this that could translate emotional expressions into harmonic and melodic direction for the spectrogram generator. But maybe that would also require more training to get the spectrogram generator to reliably produce results that followed those directions?
