RE: "i've wanted digital multi-track HD audio for over 15yrs now (i'm in my early 30s), and it's been entirely possible this whole time. THEY JUST WON'T GIVE IT TO US."
Err, for a long time, that was me too. However, for a few years now, they *have* been releasing multi-track "HD" audio, so I'm not sure if you missed it! ;)
First SACD (some of which some new releases are still taking place), but more commonly now, on BluRay (both in "Video disc" guise but now also in "Pure Audio" guise - and also, various on-line services as well (I'm quite partial to Qobuz).
Sure it was slow in coming, and the range of content is limited, but it is there and growing by the day! (thank god). The only real problem is the lack of reasonably quality of description of what you're buying, generally, by the vendor, and the odd charlatan that is selling "HD" when it's either not or barely (and/or not willing to define what "HD" means...)
