This is part of "Momo-i Sunday Early Morning Live @Shibuya-AX" DVD (AVBA-26861).
Data track contains 128kbps 44.1kHz MP3 files of the live event. I believe it is more complete than the DVD's sound track.
Again, I got these through a Momoist in Japan, who bought them from MuMo shop, in order to get points. It turned out to be a bad deal, especially for this "Sunday Early Morning Live" set, because the quality isn't there. If I got 25% discount, like I can from HMV, I wouldn't have minded as much. As for the trading card, who the heck am I supposed to trade it with!? (^_^); It's no big deal, though. Live and learn.
