Boy, they sure want our money. That's pretty scuzzy there Namdai (but not unexpected).
Thankfully, I give zero fucks about the DLC (Awakening got me to buy theirs so it has to be at least that good if not better for me to sink $ on). I'll bet the difference in Music CDs will be all of one song. And besides, the art book sounds better than the character profile book and that's probably what counts the most.
