ahh.. you know, it intrigues me somewhat.. while i've been whinging on about this 19-year old Madman 5.1 mix reissue being Lossy on the Blu-ray and we're all scrabbling about to get a replacement disc for just one Bonus Track we all had already on 5.1 SACD for many years, that there's 48 shiny new Atmos mixes of Elton's Hits in Diamonds on Apple, Tidal, etc.. tracks in Surround that encompass pretty much his entire career, many tracks that will probably never see Surround release in a similar Box Set to this Madman Anniversary set.. kinda surprised it hadn't made more impact.. maybe down the line.. anyway, sorry for the brief topic tangent but it is pretty curious, n'est pas!? i predict if SDE did an Atmos & 5.1 standalone Blu-ray Audio release of Diamonds it would be their biggest seller ever!
