Nice one for all of those info.
Japaneses albums always include more tunes than in other countries anyway. Remember more girls... OR MFJG.
Well Music Response should be just there to put a new track. And i think it is one of their best tune as well.

For a live cd, that would be amazing. They could put different gigs, from the start to now.
And OBV a dvd.. . . . . With include all the cinematic they put on the background when they play, like in the Gorillaz Demon Days Live Dvd, you can watch the live just with the movie on the background, and not the normal record of the gig.
