Except I'm completely in the Apple ecosystem but I use Spotify rather than Apple Music because there is no equivalent of Spotify connect in the Apple system. If Apple did have an equivalent then I'd have Atmos turned off as it's actively worse than lossless stereo for the kind of thing I listen to.
Apple Music doesn't work for me either, I need a streaming service that is supported by my streamer which is an important part of my main 2-channel rig, so the choices for me are Qobuz, Tidal, Deezer, or Spotify. Last week I realized that the Tidal app on my TV does support Atmos playback so I changed back to Tidal from Qobuz (which I have used for the last two years) just to be able to play music in Atmos as well. Music in Atmos will just be a side thing for me, most of my listening will still be 2-channel audio as the type of music I mostly listen to will likely never come out in Atmos.
I just have a 5.2 surround system so I can't fully judge how good or bad the Atmos mixes truly are. While some of the mixes sound great in my system and take the music to a whole another level, others sound strangely mixed as if some of the studios had a completely different level match between the channels than I have in my system, which in some cases puts way to much of the mix in the surround channels. But again, the reason for that could simply be the fact that my system is just a 5.2 system and not a full Atmos system, so the sometimes strange balance can maybe be the lack of side channels in my system. I don't know.
What type of music do you listen to that you don't think would work well for Atmos?
In my book, every type of genre should work with Atmos, it just depends on how "tasteful" the mix is done to best suit the type of music at hand. Some types of recordings will work with a more "creative" type of mixing with sound objects panned all around the listener, while others will work better if the surrounding speakers just help to create more spaciousness, room sound, and atmosphere around the listener.
What type of music wouldn't benefit from a tastefully done Atmos mix?
