I'm an audio engineer who has dabbled in atmos when it started getting popular and most of what he says i completely agree with. On a personal level, i have never found any spatial mix of any song or recording over the original mix.
99% of the time I listen to the regular mix though. I love music but I don't want to sit motionless in the dead center of an array of speakers. Music is a soundtrack to chopping onions, relaxing with a book, fixing my bike etc.
I heard a rumor that there is in fact a Parsons-mastered surround mix in existence.
Although I'm not sure I agree with you. Other human beings on planet earth are capable of remixing an album.
Meanwhile, I enjoy Steven Wilson's surround mix of XTC's Nonsuch (except the first track, in which the vocals are oddly messed up).
