A Matter of Life and Death feels almost concept-like. It maintains an unique kind of atmosphere all through its entirety, which in turn makes it hardly accessible. It wouldn't fit in the 2011 setlist because of the theme and tone of the other songs; a song, any song from it would kill the flow of the entire set (maybe they could've fitted "These Colours Don't Run" in "2 Minutes"'s place, but then again, since 2006 Maiden never includes a song from the past album in new album tours). It had absolutely no place in the Book of Souls Tour due to the theme; granted "Wrathchild" also doesn't have anything to do with the theme of that tour, but then again it's barely 3 minutes long. Nearly all AMOLAD songs are more than 6 minutes long, with the shortest one being 4:18 and very hard to fit anywhere outside of the album itself. To me, the lack of songs on tour doesn't say anything about the band's appreciation of the album, or lack of it. It means nothing.
