In the beginning of Mission 7 ‘Reunion’ when Blue Team first arrives on Genesis, there’s a soundtrack that’s just pure vocal that plays when Linda states are artificial yet organic the planet is.
Please, if anyone knows what that song is or where to find it, tell me. I have searched through the entire Halo 5 OST and have found nothing relating to it.
If you have no clue as to what I’m talking about, here’s a link to the part of the mission where it plays- https://youtu.be/VpdoscIJsUU?t=3m10s
