Maiden has some great covers.
I’ve Got The Fire
Rainbows Gold
Kill Me Ce Soir
Massacre
Hell's yes! I love that one. It should have been on No Prayer for the Dying, would go with the album's general vibe pretty well and be better than majority of its songs.
I've probably told my standing in Iron Maiden albums before, but here it goes. S/t to Powerslave: Gold. SIT and SSOASS: Very good but not great. NPFTD and FOAD: Meh. The X Factor great, Virtual XI meh. Post-reunion: Meh (all those albums have some great songs and some dross).
I have many, many controversial Maiden opinions, but this thread is probably not the best place for them.
