I'll mark the songs I dislike with *, because some of these I actually like, but they had to be picked.
*Running Free (I may say something blasphemic, but this song to me is something like californian punk. It even has L.A. jail in it)
Wrathchild (chorus)
Invaders (chorus)
Sun and Steel (I couldn't put Quest for Fire just because of the bad lyrics, it has great harmony and solos)
Flash of the Blade (verses are bad)
Heaven Can Wait (mostly because of the two minutes of whoo-o-o)
Can I Play With Madness (love it, but a bit too commercial sounding)
*Hooks In You (Why, H, for God's sake?)
*The Fugitive (not like it at all)
Look For the Truth (too much drumming in the chorus)
*When Two Worlds Collide (first time I heard Blaze's shouting of the last chorus I thought someone's out there to get me)
The Nomad (just because of the Beckett similarity part, especially because it didn't make the song itself better in any way)
*New Frontier (dead race with Hooks for the worst IM song EVER)
The Longest Day (just because of the repetitive chorus)
*Satellite 15/Final Frontier (I mean, what's the point of playing the same riff over and over, both in verses and choruses? Not to mention the robotic intro...)
*Shadow of the Valley (too many recycled ideas, bad chorus. After all, I don't remember Maiden song which jumpstarts just with an ordinary kick of the Nicko's drums)
