The Music Boxes are used for more than just directly combatting those who are Marked...

...they are also used (canonically) to disrupt the power of Bone Charms and Runes.

Gameplay wise, Bone Charms and Runes that Corvo and Daud used were not so affected, but lore-wise they are supposed to be disrupted.
