Apple Music family plan question

Hi - unfortunately, this did not answer my question. I know how to play Apple Music on Alexa devices. What I’m asking is whether it can be played on two different devices logged into the same account. Like an Alexa at home, but my phone in my office. my phone is obviously logged into my account, but the Alexa’s in my house are also associated with my Apple account for purposes of Apple Music.

Hi - sorry, that’s not quite the question. It’s whether the devices can be associated with the same Apple ID - One problem we have is that when I am away from home, and I’m using Apple Music on my phone and someone else is using it on a device at home that, they can’t both stream at the same time. I don’t know if a family plan will actually fix that, if both devices are logged into my account. The Alexas are family devices - they don’t belong to any one person, so they are associated with my account because I’m the adult. But I still want them to be able to be used at the same time as I’m using my phone.

Your response says the different Apple IDs can use it at the same time, which is not quite the same thing, because each person has their own Apple ID.

Thank you!
