can't remember if 4 or 5 was the one I had to mail in for the free score on cd. But it does come with a score. Brother had the one for Myst III, I never had it on a cd. Just wondering if thats in the cards. I can rip it myself. Just askin for others. I'm sure we are just glad we finally got IV.

Not sure what you're asking here exactly - that you wonder if GOG plans to include the game's soundtrack as a free download? If yes, then probably not. I believe they can only do that if they get clearance from any/all parties involved who own rights to it.
