There are mixes done to different levels. There are some surround mixes that are disappointingly inferior to the stereo counterpart. All well and good. But then there are occasionally "novelty" surround mixes done where you can tell no one paid any attention to any details, had any interest in the music whatsoever, or even any interest in actual surround sound. That's what this guy's mixes sound like. The Rush stereo mixes are all on point and much more accomplished than average. The Chycki mixes are bluntly insulting to the music. These are all exceptionally bad remixes.
So they're going to hide some of them behind the Atmos codec and stream stepped on lossy remains now? Great...
