Something I found when playing that no one mentions is that the boss songs actually change the further the boss HP drops, and in Draugrs case, it transitions into a breakdown that's a must-hear.
For those who are interested I found out the fight is part of the into asgard song skip to 4:10 in the song and you get the full song. And it is a little different to this version.
Me coming into the room: this first boss must do something amazing to blow me away like how ludex gundyr or cleric beast did. Draugr: *puts on sunglasses, whips out an electric guitar and starts going off* Me: *Me head bobbing with a surprised pikachu face expression*
