I have 3 mini’s, and a couple nest hub max’s plus a nicer Sony speaker with assistant… and it’s totally workable. The mini’s are totally fine for playing music in the kitchen or streaming news. They’re tiny, stay out of the way, and handle HA activations. Will they provide great audio that will blow my guests minds? nah, but ok for a bit of noise and distraction while making dinner or unloading the dishwasher. The hubs are good photoframes that provide better sound, perfectly good in my office when I just want something other than the whir of PC fans and keyboard clacking. The sony speaker is great because it’s got a giant battery, sounds pretty decent, and super portable. I take it on vacation or camping where I have a cell signal, and just use my phone’s hotspot to allow it to stream.

I don’t use spotify, I use YT Music (RIP Google Music) but it should work pretty much the same if you select it as your default provider.

Setup is dead simple, and once any of the devices is streaming you can go into the queue, and add and remove items, rearrange or whatever.
