Synth music style invented around 30 years ago on technology that didn’t exist a generation ago: "This sounds old-fashioned, the developers need to evolve."
Orchestral music played on instruments that have existed for thousands of years, in a style that’s existed for hundreds: “Finally, a modern sounding ost!” 
The closest example of that I can think of is Deekin chanting his “doom doom doom, doomydoomdoom” song in a Neverwinter Nights expansion.
