The problem is that the people who want them to play old stuff aren't the ones going to the shows, because they see the setlist with only 1 or 2 pre Clayman songs and decide not to spend their money. I'm convinced that In Flames have 2 different fanbases. One consists of fans going to see them live, and the other consists of people who post on metal-related forums.
