I bought this soundtrack after buying the OST for the first Metal Gear Solid for Playstation.
This one is not nearly as good overall, in my opinion. Part of that has to do with my opinion of the games, but the composer for this soundtrack is different than that of the original MGS. Konami Sound Team Japan did the sound REALLY WELL for the first one, but this guy (individual composer)David is not nearly as well-rounded and his choice of sound samples was disappointing to me. I really liked the sounds and industrial/ambient sound of the original MGS soundtrack -- Sons of Liberty lets me down big time.
BUT I MUST SAY, that there is ONE SONG I LOVE here, and it is in fact composed by Rika Muranaka (Japanese composer who was involved with the first soundtrack as well). Her "Can't Say Goodbye to Yesterday (Piano Version)" is WONDERFUL, and beautiful, and touching, and it is really the ONLY SONG I EVER LISTEN TO on this album.
If I could rate this one song by itself, I would give it 5 stars!!! ***** (instead of 3, for the whole album).
