Someone did an extension version of it here:

It's probably the one good thing that came from the game. On a slightly more serious note, there was a time that I was madly in love with Sarah Schachner's performance of her theme for Anthem at TGA2018. (both songs build into it - but their 'intros' are a fair bit shorter than the first example) On the other side of the musical spectrum for bandit hunting there's Vodovorot Sometimes, when I'm bored and between wars, I go on mad sprees of chasing down bandits, sea raiders and other such scum, in quick-fire, rinse-and-repeat battles, to Jackson Parodi's rendition of Ievan Polkka In the game, however, that bit of music is fantastic for when you're on horseback and the battle's lost all sense of cohesion, scattered into small clusters of combat, and you're darting about with friend and foe flying at you and past you from every direction.

Some people dislike the tonal shift when shown on film, which goes from bombastic and hellishly oppressive at the approach of the Teutonic Knights to almost light and jolly when they actually crash into the Novgorodians.

If you know you're about to have a long and epic battle, especially with lots of cavalry (and time it well, and don't mind a bit of a tonal shift) then I recommend Sergei Prokofiev's 'Battle on the Ice'
