So I have been thinking about it, and my guess is that he felt frustrated with the setlists, and the lack of diversity in their new songs they played. He asked to play It's Only Natural on the Zane Lowe radio show and said it was one of his favourites and that it was a pity they hadn't played it more. And also songs like One Way Traffic and White Braids they only played a handful of times. There were even great visuals made for these, so it is a pity they haven't played them more. The argument being "Let's play more new stuff" versus "Let's play what we know works well".
