Bloody hell mate only 8 good Maiden songs lol. There's at least 5 killers on NOTB alone lol.
I always judge a bands quality on their live performance and I can honestly say that their gigs on the NOTB & Piece of Mind tours were absolutely phenomenal - so yeah I would say they completely deserve their success.
Some of their recent output has been hit & miss but back in the 80s they were a force, no doubt.
I like quite a few Maiden songs, but I do think Iron Maiden, Killers and Powerslave are all hugely overrated albums. Personally, I didn't rate any of them. And as for Live After Death... <shudder>
Oh no, Powerslave is my favourite Maiden album and Live After Death is brilliant imo.
