At the same time, "Different World" is a great opener that doesn't reinvent the wheel, but recontextualizes it. "These Colours Don't Run" is moody with a great chorus. "The Pilgrim" absolutely stomps. "The Reincarnation of Benjamin Breeg" is one of Maiden's heaviest, skull-crushing numbers. "The Legacy" also has some questionable transitions but is overall a successful closer. And "For the Greater Good of God" is one of my favorite Maiden songs; it too is repetitious as hell, but this time the repetition propels the song instead of brake-checking it to the extreme.
BNW, meanwhile, is more heavily repetitious, but infectiously so. Rock in Rio is proof of this. All the songs slap, and despite this being the band's comeback record they incorporate a lot of moodiness into it instead of simply doing a bunch of heavy rockers. A ton of great melodies, a ton of absolutely powerhouse choruses, and a perfect balance between epic-length tracks and ass-kicking shorter tunes. They had so much energy at this time and were learning where each member fit in the overall picture. With BNW they had something to prove; AMOLAD was a continuation of the momentum. BNW has a sense of magic that I don't think we saw again until TBOS.
