In all honest, I never ever got the massive fuss about Iron maiden. Yeah they have some good stuff and I've seen their live act first hand (in '06, sadlt Trivium were supporting) and they're awesome, but their music tends to get boring very quickly for me. I prefer Motorhead and Judas rist over Iron Maiden anyday.
I remember some guy told me in the queue for the Maiden gig that 'if you don't like Iron Maiden then you're not a metalhead'. I asked him if he knew who Megadeth and Exodus were and he didn't know. He was laughed at, ridiculed for awhile, then told to shut up and fuck off by nearly everyone surrounding him.
