Well, it's getting there. Over here it's still generating more "meh" and less "ooh," but it's mostly headed in the right direction.
WMP seems to have taken a little step backwards, with too many tiny button/triangle/icon thingies, compared to a screenshot of a previous build I saw. And there's too much "You Are Here" stuff (a glowing highlight on the Library button, a breadcrumb trail, AND a treeview with a highlighted node), all of which indicate I am in "Songs..." even though I am apparently browsing "Albums."

The Windows Explorer treeview seems to have lost the tiny little triangles, which is an improvement. Either that or they appear in context (only when they need to appear)....
WMP and Windows Explorer seem to have different ideas about where things like address bars, menus, and breadcrumb trails should be placed... too bad there's no consistency there...
There is some craziness on the System Properties page - some items get a little "Windows Defender" shield and some don't...
White space on the Start Menu looks good.
