@jjoelson @matthewstoller I used to spend many hours adding metadata to my photo library. That doesn't feel wise anymore. The apps I found at the time said they could not, per Apple's policies, shuffle photos directly from the Photos library. I'm searching for that developer's explanation, but it (and his app) seem to be gone. I'll check the current round of apps. I'm curious whether I can now do what I want. /fin
