I wonder if anyone is getting some sort of confirmation of what I half-suspected from the beginning, which is that Alexa is ALWAYS actively listening. I have had the following experience several times in the last week. One of my kids will mention a song he wants to hear, I will tell him that's not in our library, but I'll put on Pandora and maybe it will play soon. So I ask Alexa to play the appropriate Pandora station and, boom, the exact song plays right off. This has happened three times in a week. And not for popular songs.
