Well, there are lots of things that are not forgotten that aren't necessarily kept alive by music. Caesar beat Pompey at Pharsalus, Louis XIV built Versailles, Matt Perry opened up Japan to the world, Perry & Henson were the first men to make it to the North Pole, Saddam is an idiot, King John signed Magna Carta at Runnymede, Michael Jordan is the greatest basketball player ever...not everything needs a song to be remembered.
