Riddle of Steel / Riders of Doom: if you remember Conan the Barbarian, you'll remember the tune (track 2). Lord only knows, but parts of it, esp. 3:50 make me think of the Requiem mass: Dona eis requiem aeternam to a pounding, driving over-the-top Williams-esque heroic tune. Rather appropriate, in this case: eternal rest grant unto them as Conan is killing everyone.
The tune is not exactly the version in the modern Gregorian tradition or even Mozart. Yes, yes, the picky adherents to the Church of Rome will point out that the 'official' order of the text is 'requiem aeternam dona eis, Domine'. However, given the glory of Latin declination of nouns, it shouldn't really matter in which order they are used.
Failing my current profession, perhaps I can turn to a life setting the Latin Mass to new settings.
et lux perpetua luceat eis.
