Google's appliance recently decided to stream Dark Piano on The Choice on Tune In when I say "OK Google, stream NPR.". Those things are so far apart I assume someone took a bribe to redirect customers for certain keywords. Lol. (Not really but it was my first thought.) Google's online advice is whenever the assistant fails to work just retrain the device. I remain skeptical that's the issue because it's not like my way of speaking has changed. Instead I have just switched to a new way to request what I need since reporting the issue via Google's vaunted customer service process seems likely to fail.
