Does anyone know the name of the music that plays in the shrine in metro2033?

Does anybody know the music that plays when you are in the shrine with Khan during the Cursed level? I tried finding it on youtube and got nothing.

I've listened to the game's soundtrack pretty extensively and I haven't found it anywhere. But then again, I think some of the songs on youtube that are supposedly in the soundtrack don't actually play in the game.
