Hi @Mitsoku Thanks so much for sharing this, really cool idea! I want to make sure I’m understanding what you’re picturing. Are you thinking about something like your phone and speakers all playing together at the same time for a more immersive sound? Or more like multiple speakers synced across a space? We do have some options today where you can group speakers and cast to them, so in a way, this partial hits your idea.  If you have a specific setup in mind, feel free to edit your post to add more details, always helpful to see how you’d use it in real life. In the meantime, your post status has been updated to Open Ideas.  Thanks for visiting the Ideas Board!  ... View more
