Alexa, where are you? You can come out now...

Alexa was playing Rumer as background over dinner this evening, when she apparently got bored and started playing "Help!" by the Beatles instead. When we tried to get her to revert to Rumer, she claimed never to have heard of the singer. Later a check of her logs showed she claimed to have heard "Alexa, play help" even though nobody had said anything remotely resembling that. Even the household AI is stroppy in this place...
