Only the tracks 1, 5, and 6 are new recordings because they chose to supply digest tracks instead of a separate data disc containing original broadcast episodes.
The real selling point for this CD (and the sister CD with identical content) is that they come with a card containing a special URL and a unique serial number that can be used to apply for a chance to attend the public recording session on 2014-02-02. This one (moe-hen) is good for 2pm event, whereas the other one (Santa-hen) is good for 5pm event.
Apparently, this was a collaboration with HMV, which is why the CDs are only available through HMV. For once, that worked out fine for me because HMV ships overseas. I'm always thankful to companies that treat foreign customers well. Also, I see they're now all out of the serial numbers, meaning any new orders will ship without them. I guess they had a limited number to begin with. I, of course, preordered more than two weeks before the release date, so I got the card.
I'm not going to Japan, so I ended up giving the number to someone I know. I hope the number gets picked.
