Devin, as I understand things, the Dies Irae was a set part of the Roman requiem mass during the classical and baroque periods, so any composer who set his hand to composition of a setting for requiem mass would have composed a version of this hymn.
Most composers of the period created settings for the Roman mass or early protestant divine services. Not sure how many of them composed requiem settings, though.
See also the much later-composed version by Verdi: http://www.youtube.com/watch?v=ZDFFHaz9GsY
I agree that Mozart's requiem mass is a masterwork of great genius. Still, it does not stir my soul the way the Cherubic Hymn can.
