Another view, more critical than mine, written by Norman Daview in 2005 when the book came out and Tony Judt was still among us.
Review: Postwar by Tony Judt | Books | The Guardian
A book this length and this comprehensive, dealing with so many histories of so many countries, will inevitably have a lapse or two, I suppose. But Davies still seems to be fighting the Cold War, while Judt is not. And this criticism seems to me off-base: "Judt, however, is impervious to religion, unmoved by music and rather complacent about non-French and non-political branches of art and culture." — especially the phrase "unmoved by music." There's quite a bit about popular music trends, hilariously opinionated so he must have cared about it.
Thanks to Andrew Hull for pointing me to this review.
