Not sure background music was used that much in this movie, and I really liked that about it. The general silence made it more atmospheric. I noticed a few songs like Ride of the Valkyries and Lacrimosa by Mozart and as the previous guy mentioned the Soviet WW2 song but that's about all I can remember playing to be honest.

Thanks a lot!

The song in the group photo scene is called "Sacred War":
Arise, vast country,
Arise for a fight to the death
Against the dark fascist forces,
Against the cursed hordes.
Let noble wrath
Boil over like a wave!
This is the peoples' war,
a sacred war!
We shall repulse the oppressors
Of all ardent ideas.
The rapists and the plunderers,
The torturers of people.
The black wings shall not dare
Fly over the Motherland,
On her spacious fields
The enemy shall not dare tread!
We shall drive a bullet into the forehead
Of the rotten fascist filth,
For the scum of humanity
We shall build a solid coffin!

The way the sound changes after the bomb drops and nearly deafen him is incredible.

Especially the second time I saw it I was struck by how much the music and just sound in general add to the storytelling.

I agree, the score was outstanding!
