About the whole The Final Frontier thing, I'm happy the album gets some love, but in a lineup of impressive supermodels such as the reunion albums, it's still the least hot supermodel to me. While it sounds nothing like its predecessor, the kind of songs were basically the same, to the point that you could rearrange the tracklist and have more or less the same order of Matter.
Let's skip the intro and we get...
Different Worlds / Final Frontier: the energetic opener
Colors / Eldorado: the single-ish, simpler song
Brighter / Mother mercy: broody song about war
Pligrim / Alchemist: fast song
Longest day / Avalon: epic with a long buildup
Shadows / Coming Home: ballad-ish
Benny Breeg / Man'd be King: bluesy epic
Greater Good / Wind Blows: longest song of the album, solo Harris
Lord Light / Starblind: oddball epic
Legacy / Talisman: epic with a long acoustic intro
Sure, stuff like "song about war" and "epic with slow intro" can be applied to any Maiden album. But, without stretching it too much with hyperbole, having a 10:10 match of kind of songs on two consecutive album is a bit weird. It's good they changed the formula on The Book of Souls.
Still, I'm glad that people like it, but you all should like Dance of Death more
