We have two HomePods, one in the dining room, one in our bedroom, and we use Apple Music on them to the exclusion of nearly all else. On occasion we set a timer, and every now and then we ask Siri about the weather, but the Apple Watch is better for timers and Dark Sky is way better for weather.
But for Apple Music, they’re fine, and for the most part, they just work. That said, I find it quite difficult to know how to talk to Siri when it comes to music, so I mostly do “Play my music,” “Play my favorites” (which maps to a playlist I’ve created I think), “Play ,” and “Play radio.”
I often don’t know album names well enough to ask for them directly, and often the album name matches a song name, so you have to specifically say “Play the album ,” which I often forget to do.
What’s frustrating is that we think of music by albums, and used to go through our shelves to pull out the appropriate CDs and put them in a 6-CD player (a long time ago). We’re pondering how to display our CD collection on a shelf in plain view so it will be easier to see and ask for specific albums.
