Honestly, I disagree! To me this is Prime's identity specifically, not 2D Metroid's, and I don't see the point of blending those two things together sound-wise when they're so different in how they play.
Now, what exactly is 2D Metroid's aural identity, I wouldn't say with certainty. All 2D games do fairly different things in that regard, except for maybe Metroid and Metroid II. All I know is that if they're planning to continue the path Dread set, I want a soundtrack that fits the atmosphere and speed of those games, and I don't think aping Prime is the way to go.
