Actually, I'm pretty sure she's for real (see below). I've heard the vocal track by itself and it sure sounds human. Although, I've heard the new Solaria demos and they sure sound like a human to me. BIAB has used some excellent singers like Béatrix Méthé in Set #8, for example.

Now with Set #18, they give credit to Synthesizer V AI voice databases, Hayden and Solaria. It looks like they started using Synth V with Set #17, but they say so in the description. If they started using these before, as in Set #15 for "The Breeze" wouldn't they have told us that it was Synth V like they do now with Sets 17 & 18?

I would be satisfied to know who wrote the song if there's no info about who sang it.

BTW, thanks for your reply, Matt.
