After listening to Death Note ost, along with Sephiroth’s one-winged angel, and Nier’s Shadowlord I think Halo could have lasting popularity in the music, besides its well-known trilogy pieces with more layered Latin singing.
Kinda weird that Halo skirts the edges of using Latin. From Tv Tropes
> The Halo series has ominous Gregorian chant playing during all of the main menu screens, and plenty of chanting during the campaigns themselves:

Several tunes also feature an Ethereal Choir. These aren’t technically examples of this trope though, since the chanting isn’t in Latin. In fact it’s nothing more than “uh” and occasionally “oo”. - There’s also a few themes (notably “Destroyer’s Invocation” from Halo 2) in which the chanting is reversed English. Then there’s the music for the live-action Halo 3: ODST trailer We Are ODST, which features someone singing in Welsh about cheating Death and ‘plunging headfirst into the afterlife’. - In Halo 2’s “Delta Halo”/“Regret” missions, the Prophet of Regret can be heard chanting the series’ theme in alien gibberish. - Halo: Reach uses a creepy droning chant several times, including during Noble Six’s Last Stand.
