Hey everyone, reporting this here since it's not possible for a Soundtrack to get news, but the Steam Soundtrack has been updated with the replacement of the old Base Game tracks to the new redesigned tracks introduced a few versions ago.
The filenames of the tracks themselves have also been changed from the format of 'number - name' to 'disc.track - name' for be more clear for those who look for the songs through file names or if the file browser you use doesn't show metadata.
