When I first heard VXI, this song immediately stood out as non-Maiden-like, and easily hateable at first. For a lot of the reasons posted here by those who only heard the song a few times.
But I kept coming back to this song because I couldn't fathom why Iron Maiden would create a song like this, and I needed to keep hearing it until I understood. One day I discovered the single version, and it was easier to digest, and I came to prefer that version for a while.
Recently, however, I rediscovered the album version, and noticed the things that are missing from the single edit. The single edit now seems too abrupt for me, and is lacking that middle ROTAM-like interlude.
Eventually I found out what SMX et al. have discovered; this song is actually pretty good.
I don't hear the choruses as the same chorus repeated 22 times. As it says in the song, "The Angel on one side, the Devil the other", I hear the choruses alternate in meaning. In one the angel is saying "Don't you think I can save you?"; in the other the devil is saying "Don't you think I can save you". Whether that was intended or not, that's how I hear it. Notice: 22 / 2 is virtually 11.
I also noticed the 17th chorus is slightly different from the others. Not sure if it was intentional or a mistake, but here (at 8:03) Blaze starts the chorus with, "Don't you think I can save you" instead of the usual "Don't you think I'm a saviour".
As for the repetition, "save your life" only appears 22 times in this song. In another classic Maiden song, "die" appears over 50 times.
