My latest Google Lyria song experiment surprised me.
I was playing back the song I had created when I noticed that the new song was longer than the standard 30 seconds. In fact, it was a full length three minute song, something only previously possible with paid versions of Lyria.
So I adjusted my prompt to take advantage of the length.
It’s probably no surprise that my latest Lyria song doesn’t touch on a couple who is never ever ever getting back together. Instead, I focused on the ICAO Doc 9303 “neutral expression” requirements I discussed in passing in this October 2025 post.
“But in one of those oddities that fill the biometric world, you can have TOO MUCH expression. Part 3 of International Civil Aviation Organization (ICAO) Document 9303, which governs machine readable travel documents, mandates that faces on travel documents must maintain a neutral expression without smiling. At the time (2003) it was believed that the facial recognition algorithms would work best if the subject were expressionless. I don’t know if that holds true today.”
That should make for a catchy song, shouldn’t it? Judge for yourself in the song “Neutral Expression.”
Wonder if the woman liked it.
She did!
