After three listens to the stereo mix on Tidal, and then one to the Atmos mix on Apple Music, I've decided I've like both the music and the mix enough to purchase de CD/Blu-ray edition.
I was surprised by the huge discrepancy in opinions about the Atmos mix that can be read over here, and now I'm even more surprised after having listened to it myself. Frankly, on my system, it sounds pretty damn good. Extensive use of all channels to great effect, and it finally does Floor's vocals justice. Inexplicably, her voice is so low in the stereo mix that it sounds totally buried by the instruments. In the Atmos mix, her lead vocals are isolated in the center channel, and they sound powerful and commanding, as they should! I listened to the whole album (which is long!) from start to finish at very high volume without aural fatigue. Also, the rhythm section sounds powerful enough to me. There's nothing about the stereo mix that sounds better than in Atmos, to these ears at least. And it can only sound better in lossless when I get the blu-ray.
