I feel the same way as TImeBandit.
When I think about "White Christmas or "Silent Night" or "Deck the Halls" I know its Christmas time and the music is very mood inducing.
Can you imagine if some power were to take away all the dearly loved Christmas songs and make new ones that didnt have all the memories that are attached to them?
People wouldnt stand for it.
I think the Org is making a mistake in getting rid of some of the memory stirring and emotion rousing through song. They really need all the inspiring tactics they can muster, rather than getting rid of some.
