Not every song or artist is remixed with Atmos in a so called immersive experience. I think Atmos in music is still somewhere new so sound engineers are still getting used to it. Some of them actually sound muffled and sunken inside the instruments. Movie surround remix engineers are already used to the sound scape remixing environment for sound effects, so definitely are better.
I found out Coldplay's Atmos remix is the best I've heard compared to others, very wide sound scape while balanced with vocal, as I experienced in my 2021 14" MBP. I also recommend Imagine Dragon's Atmos remix, instruments is very strong and definite to listen, though their vocal is thinner than stereo mix.
I myself is also trying to get an angle with the best Atmos sound scape to listen on Apple Music. When I try to listen on the top of my MBP, it sounds thin. When I sit in front of the MBP, it sound the best in Atmos.
