Feudalism: The Middle Ages Rap

I used the song C.R.E.A.M (Cash rules everything around me) by Wu Tang and made it Castles Rise Everywhere Around Me. This song is all about the different social groups that took part in feudalism and the Manorial System. Here is a preview down below.

Serfs grew food on land that was arable
Being a peasant probably was terrible
Nobles and peasants are not comparable
Clothes were scarce so undies aren’t wearable
These ages were dark and the plague was black
But nothing was as scary as a Viking attack!
Siege the castle and you can have the land
I built a castle that was made out of sand
