Jon, I have another angle on this that might be helpful. Why is surround music not appreciated, and listened to, by most people younger than boomers?
Hardware. very few people have or are buying BluRay players because everything they want to see and hear is available by streaming through their mobile devices and SMART tvs. Other than us surround and audiophile fanatics, no one cares about hi res stereo and surround content on a disc. Because of this, the availability of new ( and old) surround music on discs has been fading, and fading fast.
i sincerely believe that the best hope for seeing surround music availability survive are the recent initiatives like those between Apple, Tidal and the record companies. In the last 9 months with Apple Music, I’ve listened to more “ new to me” surround music than I did in all the years since the early 2000’s when I bought one of the first Pioneer Cd/DVDA/SACD players and gleefully listed to Roxy Music Avalon.
there are also financial benefits. For $11 a month I have virtually unlimited access to an huge amount of recorded music including lots of surround content. Included in this were the Super Deluxe surround content found on Rolling Stones GHS, many of the Elton John recordings, Abbey Road, Let it Be, Get Back, All Things Must Pass, Beatles 1 in ATMOS and many more. Do the math….if I purchased 10 of those deluxe sets on disc, at $120 ea, it would have cost me $1200. Instead I spent $132 with Apple. My only slight concern is that at the present time, streaming ATMOS is lossy compared to content on a disc, but I would expect/ hope that this will change at some point with further advancements in the technology.
Indeed, there has been a huge shift in the consumer base migrating towards streaming.
However, these boxes/collections are aimed at fans who still want the tactile/hands-on experience.
A fan who is going to stream this isn't going to bother even looking at this.
We are the weirdos, we still want books, and shiny aluminum things that spin really fast.
So it leaves me confused that they would eliminate something from a set that would be well received by those people.
I'll throw this in, too. I bought my first 5.1 discs in 2003.
I didn't get around to listening to the multi-channel layer for 5 years.
A little after that, circumstances changed, and it was easier to go back to regular stereo.
Now, it's been a few years where I once again have a proper 5.1 setup, and there is no going back back for me.
I think a lot of people just never took the time or trouble to experience the bliss of a good surround album.
I suspect if they did, there'd be a lot more listeners who would see that disc as the centrepoint of the release.
"Once you go surround,
Your listening is profound"
(I know, that needs work. I just thought of it. It's a rough draft)
