What's so hard about it? Deleting a few lines?

It's easier to just add one line in OnStart(), or wherever, and save than to open an entity up for editing, edit the entity, save (to your custom story folder), click on Entities in the level editor, find your entity, and place it down on the map and save. One function could also make the code less complex when wanting to have the monster music kick in at a certain point.
