I've decided I don't really care about the rest of their discography. But I really like a lot of what I have, so I'm good.
EDIT: And in case anyone asks, I have Killers (which I don't really care for) through Seventh Son (which I also don't really care for, but I like pretty much everything in between) and all the reunion era albums.
Bosk, if you're a fan of the reunion era, which I recall being the case, and if you haven't done this already, you might at least listen to a couple of
X Factor tracks to see if you like the general vibe and Blaze's voice. That album is definitely not for everyone, and if you said "I don't like the tone" or "I don't like Blaze," then I would completely understand. But that album is basically the first prototype for the proggy stuff they would do in the reunion era, and it's one of my personal favorites
If you have
Rock in Rio, though, you already have almost all the absolutely essential songs from the 90s: Sign of the Cross, The Clansman and Fear of the Dark. The only other one from the 90s that I'd say is definitely worth checking out even if you ignore the albums is Afraid to Shoot Strangers.
From the debut album, you might like Remember Tomorrow (I assume you already have
Live After Death and thus The Phantom of the Opera). Beyond those two, if you're not a
Killers fan, you can safely assume you're not missing anything spectacular.
I totally agree with you on
Killers, by the way. It's one of my least favorite Maiden albums and it doesn't really do much for me. I rarely listen to it.
