Prowler vs Aces High ( Prowler is a very, very good song but vs Aces High...sorry)
Remember Tomorrow vs 2 Minutes to Midnight (almost the same as above, I really like Remember Tomorrow but vs 2 Minutes...sorry again)
Running Free vs Losfer Words (neither are great songs but the studio version of Running Free is really boring and lifeless)
Phantom of the Opera vs Flash of the Blade
Burning Ambition vs The Duellists (I always thought The Duellists to be one of the most underrrated tracks specially that long instrumental part that is awesome)
Transylvania vs Back in the Village
Strange World vs Powerslave (sorry again part III...I might be in the minority here but I really love Strange World but once again no chance when it's against a Top 15 Maiden song imo)
Sanctuary vs King of Twilight (Sanctuary is one of their most boring songs imo and even if I can't say I'm a fan of King of Twilight, between the two, I'd take the cover)
Charlotte the Harlot vs Rainbow's Gold
Women in Uniform vs Mission From 'Arry (just because a choice has to be made, Mission is funny but still not a song...Women in uniform is at least a song with music...but that's it, boring and repetitive)
Iron Maiden vs Rime of the Ancient Mariner
9-2 for Powerslave
