Myst Masterpiece is not the same as Myst IV. It's an updated version of the first Myst with 16-bit graphics instead of 256 color graphics and better sound quality.
The Limited Edition of Myst IV was released in the US.
The "Limited Collector's Edition" of Myst IV was released in the UK.
The "Limited Collector's Edition" came with a bonus DVD and a small deck of playing cards, but as far as I know it didn't include a soundtrack CD the way the US Collector's Edition of Myst III did.
EDIT: I found more info here

First i can give you the information about the content from the package:
-the game (2 dvd's), a blue and a red printed ;-)
-a bonus dvd... with the soundtrack and some quicktime movies. I'm very angry that my standard DVD Player doesn't play anything from this :-( there are some folders with SOME soundtrack mp3 files...i think they hadn't enough time to make it better... down.gif
-the playing cards aren't a "must-have", too, it's a normal 32 play card set (a french one). only with "Myst -4" printed on the backsides. I also get a wrong printed front size...
the collectors edition isn't really worth its prize! only packaging as a MYst Book looks nice.
So apparently with the "Limited Collector's Edition" you get some of the tracks as mp3's, but not all.
Found a track list for the CD here
http://en.wikipedia.org/wiki/Myst_IV:_Revelation_Soundtrack
Here are the tracks included as mp3's on the DVD:
1 Main Theme
2 Tomanha
3 Serenia
4 Spire Prison
5 Haven Predator
6 Sirrus
7 Bomb Factory
8 Haven Predator 2
11 WBV Welcome
I don't know how these relate to the track list of the CD.
