I think that some famous Soviet songs like Katyusha came to be popular and that the Soviet anthem (which I think is still the best sounding anthem ever made) was first created during the war but what happened in other countries and what was the lasting legacy on troops and civilians?
the category of music has a wide variety of answers and countries, many countries took to making songs making fun of the germans as a way of boosting morale for the civilians. In the US one of the most popular songs in 1943 was Der Fuhrer’s Face by Spike Jones which features such lines as "we Heil fart Noise Heil fart right in der fuhrer’s face"and anti Japanese music was also quite frequently made too, My Grandma remembered being 9 and her and a friend at a local function had to memorize and sing the song We’ve gotta slap the dirty little [insert insensitive racial term here] . Other countries had parody music as well, Britain had the song Run Rabbit Run which was one of Churchills favorite songs and during the war it had some of the words changed so one stanza becomes Run Adolf Run and the song Run Rabbit Run was very popular during the blitz, The Soviet Union also had one song called No Mercy to the Bastards which like other parody songs was making fun of the Germans. The Germans also had a small category of parody songs too with one called Siegfriedlinie which was a parody of the british song We have to hang the washing on the siegfried line. Serious songs existed too, the Soviets and Germans put out the most and even in modern russia some of the Wartime songs put out are still popular such as The March of the Soviet Tankists and March of Stalins Artillery. Music for many was a way to escape some of the harsh realities of the war and soldiers frequently had Record players along with records that would be played. Sorry for the length of this post I could go on longer as ive studied ww2 music heavily but this is just a few examples of music during the second world war
That word’s used in the news reports that I collect from the time.
It is a frequently used term within wartime music and terminology amongst far worse ones
