I think the vast majority of the humongous crowds for the IT tour came for the hits on IT and the previous album, so the setlist had to focus on those. I think including the full ITQE was quite a deep cut, even more than Apocalypse onward, so I was very happy with that.
As long as they produced new music, they have always preferred to play new material. Fair enough. The 2007 and 2021/22 tours didn't have that, so the setlist was put together without that "new album out" thing. Nevertheless, fans will always complain and want different songs ....
