This makes it sound like the bulk of requests to D-V you see online as being for easy listening material, which I think is an irresponsible characterization. Of course they're going to get those, along with requests for classical music, because they have a long history (and excellent reputation) with that material.
It's worth remembering that over the last 3 years that they've also released more music from "popular" genres on SACD than most of the other reissue labels combined, and I've seen just as much praise for (and requests for) music from those genres in D-V's social media channels as I have for the "dreaded" easy listening/classical releases. And that doesn't even count what goes on here, where hundreds (or possibly thousands, if you count the lurkers) of people are constantly clamoring for further releases.
So I think it's safe to say that more than three years in, "popular" SACD releases aren't some temporary 'off course' derivation for the label, nor are they blissfully unaware for the demand for more of this type of thing. Look at the Analogue Productions release of Jimi Hendrix's Are You Experienced, which has been languishing in pre-order status for nearly a year and a half now as an indicator of how difficult it can be to get a high profile pop release out the front door, and appreciate the fact that the next time D-V makes a release announcement that you'll probably get a shipping notice within 24 hours of of ordering. If they can issue easy listening/classical releases (which are presumably low hanging fruit, in licensing/financial terms) in the meantime while they wait for the popular 'big guns' titles to iron themselves out, that's a win/win situation for everyone - a label in good finanical health can take calculated risks on other titles (like the ones they marked 'limited edition' perhaps?) and at the same time make these easy listening and classical quad mixes available for the first (and possibly only) time digitally.
Is the waiting the hardest part? Absolutely, and don't I know it - I got the news about the Derringer and Guess Who titles nearly a year before they hit the streets! But you have to trust the wisdom of any label that's been in business for more than 20 (twenty!) years, even if, in the short terms, the releases you want don't come in the order you want them.
