I was and am still a big fan of 0083. It was the first Gundam Series I ever watched from fansubs. It was the pinical of what I believe defined the 90s mecha animation mechanics and detals that would follow many other anime Sunrise would do into the 90s.
But as purveyor of movie and program music, I also became aware of how much 0083 ripped off whole tracks from other movies. In fact the latest piece I became aware of came from Death Wish 4 (although apparently the Hollywood studio used these tracks in other films of theirs too).

He also used many pieces from James Horner's Glory, which came out 1 year before 0083 happened. I have the original 0083 soundracks and I do think they credit James Horner in the covers. Also if you notice in many of the releases of 0083 over the years, the soundtrack has changed sometimes replacing or outright modifying certain pieces, so they sound like but are not the same as the original Hollywood tracks they were copying.
