well the tracklist for the 2nd disc is not 100% confirmed yet so hold your horses on that !
if you realise the packaging for the 2CDs + photobook , it's kinda like the limited edition for ARASHI's All the BEST !
from left to right : photobook , slipcase & digipak
& yes that's my copy xD
I think for ayaka's case , it might not be a digipak for the album but never say never
