if we really wanted an all-Ayu thing and the other singers are a "boring prelude" or whatever... avex should have made a "a-nation 09 SPECIAL: Ayumi Hamasaki mini concert!" DVD to shut us up.
But no. They decided that, "Oh we will just let Ayu have the same amt of songs shown in TV, and we will cut a little off the rest!"
I remember someone saying that the TV broadcast is just about the same as the DVD, that's why they also didn't bother showing other songs from other singers (seriously, Kuu's ECSTASY, Tohoshinki's Survivor? We have seen those on WOWOW), then they shouldn't even have bothered putting a single Ayu song in it then.
I don't think it's wrong to put all of 8 Ayu songs in the DVD, but I think it's wrong to just limit one song to each other artist, and also the song being shown on TV already. It's ridiculous, unfair and biased.
