Fortunately, now when you listen to an Atmos album in Tidal, at the end of selection Tidal stops playing. Will have to review if there is any setting for that.
In the beginning, the Tidal App will continue with other "suggested" tracks, that are inevitable non-Atmos and the high volume level set was too high for the stereo tracks, thus bumping from your seat.
I have only Tidal, as an early subscriber before Apple started Atmos. Now I continue with it, because Apple would be somehow redundant for Atmos and I'm not an Apple Guy. Some Atmos titles exist in Apple and not in Tidal. Also fewer in Tidal and not in Apple. I don't have any statistics for that, but it all depends if you like the music style of the missing ones.
At the end, If you're an Apple Guy, have an Apple TV, even have video Apple TV streaming subscription, the decision would be immediate. If not, and you start with all this, a Fire TV stick is the cheaper device (for Tidal, and no for Apple, I think) and you could start a trial on Tidal. Then Tidal is a little expensive, but the amount it's just only like "paying some beers with the friends", I said to me
