I wanted to post this just to get it out of my head since it's bumping around. Okay, so in Skyrim there are two main pieces of musical propaganda: The Age of Agression/Oppression depending on whether or not you're in a town controlled by Imperials or Stormcloaks. But what about Ragnar the Red. At first glance, it doesn't seem political at all:
There once was a hero named Ragnar the Red, who came riding to Whiterun from ole Rorikstead!
And the braggart did swagger and brandish his blade, as he told of bold battles and gold he had made!
But then he went quiet, did Ragnar the Red, when he met the shieldmaiden Matilda who said...
"Oh, you talk and you lie and you drink all our mead! Now I think it's high time that you lie down and bleed!"
And so then came the clashing and slashing of steel, as the brave lass Matilda charged in full of zeal!
And the braggart named Ragnar was boastful no moooooree... when his ugly red head rolled around on the floor!
So, a loudmouth ginger getting what was coming to him, right? Maybe more than that. First consider the name. Ragnar the Red, as in the color associated with the Empire. And then where he's coming from. Rorikstead. Namely a town purchased by an Imperial war veteran. What if the song is more symbolic of the sons and daughters of Skyrim getting tired of an old and increasingly impotent Empire living off its past deeds, rising up and slaying it?
I'm probably reading way too much into it, but just had to put that out there and see if anybody else had thought of this.
