It's fairly trivial to keep the recommendations consistent depending on the latest request, not just the logged user. Pandora does a good job at this. We have it on our Alexa and at dinner, we take turns with the kids requesting songs. If we stop requesting, it keeps playing an internally consistent series based on the latest song we asked for. So if it's the kids' choice, it's a never ending row of Kids Learning Tube :-)
