music subscription

I have my Apple Music subscription for one person, me. I can't play on two (personal) devices; which is understandable.

However, I am thinking of buying the HomePod for my living room.

Say someone play a song from the HomePod, I use my phone to listen while I run.

Can I use both devices at the same time? HomePod and iPhone

or does the subscription will recognize it as one device as well as the laptop...?

Thank you
