Heh, first, I thought this cannot be decided by me. But then I realized that:
1. The X Factor
2.-5. Iron Maiden, Killers, Powerslave, A Matter of Life and Death
6.-10. The Number of the Beast, Piece of Mind, Seventh Son of a Seventh Son, Brave new World, Dance of Death
11.-14. Somewhere in Time, No Prayer for the Dying, Fear of the Dark, Virtual XI
Hmm, as you can see, something of the dubiousness (is it the right word for not being able to decide?) has remained. But the first is quite clear. Blaze is there (but this not helped the VXI), Sign of the Cross is there (my most favourite IM song) and other songs are quite good too. My first IM album. Somehow lacks the repetitiveness of the VXI, it is dark - that is what I like. Several of the X Factor songs, I tried to learn when I started learning guitar (and they sounded strangely nice using accoustic guitar combined with my poor skill of that time and my brother's voice - far from Thingfish's excellent interpretation
I understand that there are lots of fans who do not like TXF, but in the end, it is only a matter of tastes.
