I could really care less about Lossless, to be honest and I'm very much over all this obsessing about it on this website. People do realize that we're talking about the tippy top tier of audible difference, right? It's absolutely not going to be detectable in many listening situations -- and even then, more for people who really want to actively listen for it with trained ears and high-end headphones or loudspeakers. No shade to people who are legitimately into high end audio -- more power to you. But I think a lot of casual music listeners are suddenly obsessing over Lossless just because they heard it's better and they have to have it.
What I want to know more about is spatial audio -- which tracks have it, whether it gets incorporated somehow into "legacy" tracks. That is a feature that would make me consider switching from Spotify. The limited amount I've used it on my AirPods Max, it's a really immersive, cool experience.
