It´s not known, if the dictator really liked the songs about him. Maybe they were just made by the artists in order to survive him.
Stalins favorite song was “Suliko”, a sweet georgian song about a dead woman.
Hitlers favorite song was “Badenweiler Marsch”, without text.
If you compare both with Chuchills favorite song, the swinging “Lambeth Walk”, it gives a hint on his humor.
I would like to know the favorite songs of Roosevelt and de Gaulle – if they had them.
