Have had an Apple TV and upgraded each generation since the beginning but just got my first HomePod. I use my Apple TV as the hub for Apple Music because I like the big screen for navigation and I like the album art on the screen when I'm hosting a party. I'll now have a few HomePod speakers connected to Apple TV- one out by the back deck, one in the dining room, etc. Let's say I'm hosting a party and I'm in the backyard....can I walk up to one of my HomePod's, tell Siri to "play the Songs Of Summer playlist everywhere" and have it do exactly that for the other HomePod's as well as the Apple TV? Or do I really have to get up, go into the house, pick up the remote, and navigate through Apple TV to change the music to a different playlist? Can I use one of the HomePod's to make that change not only to the other HomePod's but also to the Apple TV standing out by the pool using only my voice?
