It's really weird, right? To my knowledge, it definitely isn't common practice to completely swap out a game's soundtrack like that, especially not between different editions of what is essentially the same exact game with minor gameplay tweaks!Wait, what? They changed the music for the Greatest Hits rerelease? Was making changes for those common? I know the Director's Cut is different from the original version, but that at least has a different title. Are there other examples of the GH editions of games being different? Was this just a PS1 thing, or did it continue on to PS2, PS3, etc? I don't recall Nintendo's various GH lines making changes...
And on top of that, the redone RE1 soundtrack was "composed" by Mamoru Samuragochi, who has since been disgraced for faking a hearing impairment and didn't even compose his own soundtracks; instead he secretly had them written by someone else (this is a pretty good summary of the whole story).
