Listened to A Passion Play by Jethro Tull last night, listening to Simon Rattle's Mussorgsky's Pictures at an Exhibition now. Really digging it, hope they add more. They have some Bowie on there...Diamond Dogs, Young Americans, others, but no Ziggy Stardust...similarly, they have Thick as a Brick but no Aqualung...but they do have the first and fourth Foreignor albums...two by Ornette Coleman, didn't see a whole lot of jazz on there, yeah, I'd say it's about 50% classic rock. The only Kate Bush they have on there is 50 Words for Snow which is a weird choice.
Oh, look, they have the first three from Black Sabbath -- I actually have the 24/96 of those, I can actually compare those.
