Andreas Waldetoft have made great work on it. This game has propably best music that I have heard in any 4X Space game. Stellaris would not be same game without this music.
For battle music nothing beats the Battlestar Galactica OST.My only complaint is that the soundtrack doesn't have enough "battle music" to fit the mood of total warfare or a frantic massive battle or enough "sinister" music to fit the more malevolent empires. That being said what is there is absolutely gorgeous and fits the exploratory mood perfectly.
I like the mood of the Stellaris music much better than the metal mixes they have added to other titles, which is always a jarring contrast when a track changes.My only complaint is that the soundtrack doesn't have enough "battle music" to fit the mood of total warfare or a frantic massive battle or enough "sinister" music to fit the more malevolent empires.

I honestly prefer the Daleks' leitmotif to the Galactic Empire's for sheer menace but so far I've never met an A.I Empire that really holds a candle to the omnicidal bloodlust of the daleks.For battle music nothing beats the Battlestar Galactica OST.
For ominous / threatening / evil empire you can always queue up the star wars OST right?
