When you cannot listen to music without reading something, then I suggest this review by Philip Davis of the autobiography of Paul Feyerabend, that starts in World War 2.
When some people are calling for another war of religion, let us remember Country Joe & the Fish in the song I-Feel-Like-I’m-Fixin’-to-Die: asking What are we fighting for ? This song is so part of collective memory that I was surprised to discover that Joe McDonald still lives and thrives, see his website.
There is also a great song by Thanos Mikroutsikos Mia pista of fosforo (“Dancing Floor made by Phosphor”), with a movie that depicts Greek people fleeing from either the euro or radical islam. You would not want to get in the same situation.
Subsequently there is Manos Loizos in “Ola se thumizoun”, which seems a love song but might also refer to a letter by a soldier who will not return from the battlefield. There is a simple version by Loizos himself and a concert version by Haris Alexiou who is clearly in pain for the sorrow that the letter causes. Here are the lyrics by Manolis Rasoulis.
