I'm sure eventually you can, but I don't think triggering emotions is the correct "KPI" so to speak.
On social media platforms, typically the most popular content triggers the strongest emotions. It's rage-bait however, or sadness bait, or any other kind of emotional manipulation. It tricks the human mind and drives up engagement, but I don't think that is indicative of its value.
To be clear, I'm certain that's not what you're doing, and the music is good. But I think it's complicated enough that triggering emotions isn't enough data to ascertain value.
I don't know, exactly, what combination of measurements are needed to ascertain value. But I'm confident human-ness is part of the equation. I think if people are even aware of the fact a human didn't make something they lose interest. That makes the future of AI in entertainment dicey, and I think that's what fuels the constant dishonesty around AI we're seeing right now. Art is funny in how it works because, I think, intention does matter. And knowledge about the intention matters, too. It maybe doesn't make much sense, but that's how I see it.
