The X Factor
This album has definitely been a 'grower' for me. I never really cared about it earlier due to stylistic changes from the previous albums. But now I do enjoy listening to the entire album and be able to appreciate it dark-melancholic tone. My favourites being Man On The Edge, The Aftermath, Judgement of Heaven, Sign of The Cross and to an extent Blood On The World's Hands.
Seventh Son of a Seventh Son
This might be surprising but when I was first getting into Maiden, I was familiar with a more straightforward music of theirs from the albums before it. But when I first heard the synth intro from Seventh Son (title track), it didn't click with me at first and I found the other songs from the album a bit outlandish. Only later did I realize it's beauty and now it is in my Top 5 by the band.
A Matter of Life and Death
Again, may sound strange but I didn't care much about it due to it's overall tone and "atmosphere". But again, now its not only in my Maiden Top 5 but if you ask me that hypothetical "desert island discs" question, I would surely add it in my cart, without a doubt!
Senjutsu
The songs being too long and a very weird first impression from listening to The Writing On The Wall, didn't really make me a fan at first. But after sometime, giving it a proper full listening, made me realize that it is truly a heartfelt record (though with it's own vices here and there) and still a respectable release by the band.
