Subscribed. I still view CalBear's A/A-NW (regular TL and post-script) as the ultimate word, but what you're doing is something very interesting and unique indeed. Hope you can continue this TL; I'd like to see what's happened to Croatia, considering how vague CB was when he answered questions about it (which itself was pretty rare).
It's also nice to see that you're focusing on popular culture, another thing that I felt CalBear mostly ignored in his timeline. I'd definitely like to see the alternate version of heavy metal that CB described and see what equivalent (if any) punk rock and all its outgrowths has in this Cold War-less world.
I'd be willing to bet with over a decade to carry out their sick plans that there would be no Serbs left under Ustasha rule. They'd all be brutally killed, deported to Germany to be worked to death or converted.
Also I'd like to see the horrific effects of Generalplan Ost on Poland and the occupied USSR in terms of the deaths and the destroyed cities.
In CalBear's TL the Nazis got close to completing GP Ost with a death toll of over 80 million Slavs in less than 20 years.
50% of Latvians, 75% of Lithuanians, 65% of Ukrainians, 75% of Belorussians, 80-85% of Poles, 50% of Estonians, and 75% of Russians were designated to be worked to death or starved with the survivors enslaved on German farms.
What do the survivors do considering their respective nations have been obliterated and their homes and cities destroyed brick by brick and all they've known for over a decade is hard labor on German settlements as serfs?
Something about the Nazi medical experimentation program which became similar to OTL Unit 731 in terms of scope and scale would be nice too. A defeated Soviet Union and over 100 million subhumans to "expend" means that Nazi doctors like Mengele will have all the test subjects they could ever want to carry out experiments, weapons testing etc.
