I went to check my games list, and noticed that the Soundtrack extra was removed. I managed to download it before it went down, but I'm curious as to what happened. It seems to have vanished when GOG did the transition.

Yeah, not cool if it was once here. I know a high-quality soundtrack is a big selling point for some people, so I think GOG would be smart to try to get it back.

This has happened a couple times. I've begun to make sure the soundtrack is the first thing I download after buying a game so I make sure to get it.
