Only tangentially related to UW and Space Opera stuff, but absolutely inspiring: Christopher Tin’s Sogno di Volare (“The Dream of Flight”). It’s the main theme song of Civ 6, and while it’s not quite Baba Yetu (because you can’t follow up Baba Yetu), it’s still amazing and a very worthy theme for something as uplifting and grandiose as Civ.
“When you have taken flight, you’ll decide that this is where your heart feels at home”.
[Edit] Actually this would make for an AWESOME opening credits of a Star Gate-ish UW game!
I’m going to just go on pretending Civ 6 doesn’t exist.
