As I said, it was an impression, not a claim. I don't like or care about Apple products and services since the early 2000s with the iPod and iTunes which made everything proprietary and closed. I think they also had the habit of only keeping one version of a song even if there was different versions, mixes or mastering. Everything was locked to a computer or device and needed iTunes to be transfered. This is the kind of business practices that makes me not take Apple seriously in the music field. I just figured it would have been the kind of thing they did to hype up their Atmos catalog. Good for those who subscribe to Apple music then if it isn't the case.It's not my intention to single you out by any means, but I've read that claim elsewhere and I'm not sure where people are getting the idea - the vast majority of them appear to be genuine remixes from a multitrack source, though obviously that doesn't guarantee they sound good. Many (most?) of the Atmos titles recently issued on Blu-Ray disc - examples include Tears For Fears' The Tipping Point, Kiss' Destroyer, The Band's Cahoots, etc - are also streaming on Apple/Tidal and clearly use the same mix/master.
