Well it's kinda th problem that they've gathered more and more songs over all those years that one concert hasn't enough time for all old and new hits...

I think the weather was really a problem for the DVD. They has to use a lot of playback. I really wonder how the sound was on that day. I attended a stadium concert with rain before. When it rains so much there are a lot of sound problems.
I wonder if they plan a dome DVD too...? Well, I don't really think so.
Which songs do you think/know are definitely playback? Besides Aiba-chan's solo -.-
