Crusader Kings II's music was composed by Swedish composer Andreas Waldetoft. The original soundtrack contains 24 tracks, including the main theme.
In addition, Paradox has released some music DLC which adds tracks to the game's soundtrack. Not all of these will play for all characters and some have quite restricted conditions, such playing an English character or playing as a Muslim. Since 2.5.2, context-sensitive music can be unlocked for all characters through a sound option; i.e. when toggled off all music can play disregardless of whether the conditions for playing it are fulfilled.
Paradox Interactive has released sixteen music DLC packs, plus a bonus song for owners of Crusader Kings: Chronicles. Unless noted otherwise, the songs in the DLCs were composed by Andreas Waldetoft.
