Further back than that. People have been saying multichannel music was the future since the 90's, when home theater started to get huge. (In fact I'm sure you are aware people have at various times said multichannel is the future going decades further back...QUAD sound and all that).
Let's face it, the vast majority of people who listen to music have no desire to surround themselves with speakers. Ain't gonna happen. Speakers have gone to earbuds/earphones or even to MONO (the ubituitous smart speaker). The arrow is headed in the other direction if anything.
If you look at High Fidelity/Stereo Review around 1970, you will find lots of promotion of 4-channel surround. And don't forget Dynaco's quasi-surround, 4 speakers, center channel, back [summed out of phase] channel. It only required a routing box and two more speakers.
The reason surround doesn't catch on is the reason why audio manufactures want it to catch on: it's more stuff. Normal people want a small, unobtrusive device that does everything.
In answer to the OP: The last physical disc I bought was a used, $2 copy of "Gord's Gold", Gordon Lightfoot. There's a very recent documentry on Gordon Lightfoot, it re-aroused interest in his music. "If You Could Read My Mind" [aka "Sit Down Young Stranger"] is one of my all-time favorite albums. I used to be a "collector" [though hoarding was never all that far away from my perpetual squirreling away of LPs], but with streaming, I no longer have to buy something new to hear it. I've got something like 1600 CDs backed up on my computer, on a hard drive, a tiny flash drive and a tinier Micro SD card. Almost all of the things I listen to repeatedly are in that collection, so the urge to get more stuff just ain't what it used to be. Once I rip a CD to the computer, I stop playing the CD, it just isn't as convenient and the sound quality is identical.
