That’s odd. I downloaded the UK iTunes version and it has the same order as the CD (as shown on Amazon.) Perhaps only the US iTunes version is different.
iTunes sucks anyway. They offer most of their stuff at lower bit rates (128) and I assume they still have their digital rights management on much of their stuff. Screw that.
I rarely buy downloads, but when I do, it’s from Amazon. Everything i’ve seen has been 256 and once you buy it you can play it whatever computer you want. Much better.
