Is Victim of Changes considered to be Priest's magnum opus?
The problem is sort of in the title. None of those are really their "signature" tunes. They are more "epics" or "magna opera" (yes, that's one of the plural of "magnum opus"). I would say "Victim" IS Priest's magnum opus, but not their signature tune.
To me, the "signature tune" is the song they play at a Super Bowl halftime, or for their one appearance at their Hall Of Fame induction.
The "signature" tunes for me would be:
- Maiden: The Number Of The Beast
- Black Sabbath (Ozzy): Iron Man (or, maybe, Paranoid)
- Metallica: Enter Sandman (or, maybe, Master Of Puppets)
- Priest: Breakin' The Law (or, Living After Midnight)
(I put those in order of my preference, by the way).
