This gives me a deja-vu...
The same thing happened last year with the soundtrack of Hearts of Stone and Blood and Wine, CDPR had some sort of exclusivity deal with itunes, google music, etc.
For a company calling themselves anti DRM, DRM-Free... this really doesn't look good.
No, unfortunately the extended soundtrack from the base game and the OST from Hearts of Stone are not available on GOG (or Steam). Same will happen with Blood and Wine OST.
You can only get them in Spotify, Apple Music, Google Music. :disgust:
