I don't consider myself an audiophile, so I think the 'Lossless' label next to the track name just has some sort of placebo effect on me.
I stream from two sources NAS and Apple Music. NAS I have around 7-8GB of FLAC, Apple Music I used only to play Dobly Atmos music, or at least until the 6 months trial is up and there isn't another trial or some sort of deal for $6 for another 6 months or something. That being said some Dolby Atmos tracks especially ones for older songs sounds terrible. They are excessively mixed to the point that it changes the dynamics compared to its original. Modern music sounds great with Dobly Atmost, but the stuff from the 60s-70s and even some 80s-00s track sound terrible to me. I do not need my Gordon Lightfoot 'modernized,' so whoever Apple got to mix these to me missed the mark.
