vv221: You should not trust what is written on the store pages, these descriptions have probably never been updated ;)
I only bought Galaxy Edition Upgrade Pack, never the Complete Soundtrack DLC. But I have access to the full soundtrack from my GOG library, including the tracks added with the expansions.
As far as I can tell, buying either Galaxy Edition or Galaxy Edition Upgrade Pack automatically adds Complete Soundtrack to one’s GOG library.
Further to my previous reply to this.
I've just bought the
Galaxy Edition Upgrade Pack as it was on sale for $4.69 AUD.
And yes you get a very large Soundtrack zip file (2.38 Gb), in Extras.
You also get a Soundtrack EXE and BIN file (2.36 Gb) and a Linux variant of that, both in the DLC section.
Not sure if they are the same thing, but the installer version maybe installs into the game itself?
You also get a novel zip file in Extras, and an Infinite Frontiers ebook in the DLC section.
Similar duplicate with this maybe, though quite why you would install an ebook into the game I don't know?
Or maybe the EXE versions are some kind of Viewer (player).
Then there is the Artbook and Wallpaper in Extras, and the Arachnoid Portrait Pack in the DLC section (Linux version as well).
Now it seems I have the complete lot of Stellaris goodies currently available at GOG.
EDIT ZIP file OST content.
59 MP3 tracks.
55 FLAC tracks. (no flac version for the Ancient Relics OST)
3 OGG tracks. (Nemesis OST extra format)
3 WAV tracks. (Nemesis OST extra format)
And the web page for just the Complete Soundtrack, now says 'Buy as a gift' for me.
