More of my favs!
"Space Cruise (title)" from FTL (2012), composed by Ben Prunty
https://benprunty.bandcamp.com/track/space-cruise-title
The soundtrack to FTL is really wonderfully cohesive, and has interesting use of theme and callback. I recommend listening to the whole thing (and playing the game!) if you like this track.
I can't remember who said it, but something that really stuck in my head is the line "One sign that a composition is truly great is if it also sounds good in re-arrangements."
