I own the soundtrack to Prime 1, and there's a fair number of tunes that are mostly percussion and a techno instrument or two.
That is not ambiance. Ambiance would be birds chirping and babbling brooks and other such environment sounds. Not Techno instruments.
Do you not know what the term "ambient music" means? Because it's basically exactly what he's talking about.

Ambient music.
Could have let this die, but you didn't. This stuff on this site sounds nothing like Metroid Prime, at all. I tried playing a few and the music in some of them didn't even START until two or three minutes in. And As I go through the soundtracks for all of the games, I can only find some tracks that are even anything like this stuff, and most of those are like "Corridor B" or stuff that would play in hallways to transition in between areas.
And this is why I never get into real discussions of music, because the next thing that's gonna be shown is some kind of genre chart or some kind of definition of "ambient music" that somehow includes Linkin Park or Thelonious Monk or Star Wars. It's just too much useless knowledge that really isn't worth knowing. All I can rely on is my ears and to my ears Metroid Prime sounds nothing like the exemplar given.
So can this please die now?
