I ended up getting Hopeful + Bold for mine. My top songs were:

1. Unser Panzerdivision - Erich-Weinert-Ensemble
2. Let's Go - Red Army Choir
3. We Are the Army of the People - Red Army Choir
4. Heart of the Android - Orden Ogan
5. The Sacred War - Red Army Choir

I honestly had no idea how much I listened to the red army choir
