I have some russian and german themed playlists,you can use them if you want,but i dont care if you dont.and be aware the german one (partly russian) is not very time period accruate if thats what your looking for,as it has a lot of music before and some after,but the general vibe is similar.and if you cant handle the prospect of this type of music then just dont listen to it
