The Metroid Prime theme definitely fits game well and I like it for all the reasons you mentioned. Maybe I'm just not as into chanting as a whole.

As for The Last of Us, if minimalist music (and some droning, especially the undertones) isn't your thing, then you won't like a lot of it. But again, part of what I love about it is how well it fits the tone of the game. Especially that main menu theme. Having played the game (not finished it, but I will once I work up the will…), I really think it would've failed if the soundtrack got too bombastic. I'm will to admit that in music/game soundtracks, I often like music I otherwise wouldn't if it helps to set a good mood or fits really well. Red Dead Redemption is probably the best example of that.
The other piece I posted from the Last of Us, though, is not nearly as droning, it's mostly acoustic.
