but I'd agree that they use chorus much more effectively that the prequel scores (where CHOIR simply denotes EPIC).

What about TOD?

The same language (Sanskrit) used for TOD's chants, was the same language used for DOTF (which in the original intended score, was used much less, and only in instrumental guises, except for a short bit in the very middle of the duel, and the end credits/concert suite)

And he also put enough effort to actually write lyrics with meaning instead of "Oooh" and "Aaah"

DOTF's lyrics were from Battle of the Trees ("Under the tounge root, a fight most dread, while another rages in the head")

BOTH's lyrics are translated to "Greivous are the crimes of the Empire"
