I really don't understand why people keep complaining about the set lists. Have you guys ever thought about having a think about what other bands do? Most bands that are on tour do EXACTLY the same thing. They create a set list for the tour and perform it at every concert, with slight or no variations. Back in the 90s when X Japan were performing, they were probably doing what they are doing today as well. It is just because we can get information from all these concerts on the tour, like their set lists and video clips, that we have come to expect something different.
A good, current example I can think of is Coldplay. They have been playing quite a lot of concerts before and since their album has been released, and they have also broadcast a lot of them live or later over the internet. I have watched quite a few of them and they all have a similar set list, with perhaps a coulple of different songs played every now and then.
For those of you that completely disagree with me, I wonder: Would you be dissapointed if X Japan came and played in your city, and they performed a similar set list? If so, I think you should consider yourself lucky. I am sure that there are a lot of people on this forum and all over the world that would like to see them play live, even if they play the same set list that they have prepared for this tour...
Just my thoughts.
