There’s this ambient song from a level in one of these games with female vocals. It was very somber as opposed to the usual exciting and bombastic sound of other tracks. I’m trying to identify it from when I heard it as a kid, which is the last time I heard it, but have had no luck with browsing the soundtrack MP3s or YouTube videos. I loosely remember the level having a sophisticated look to it, I was on a catwalk looking at another catwalk and I believe it was indoors. The scenery was white.
Edit: it’s similar to the Halo 4 theme.
