Why should we want things that doesn't sound like Halo? The audio is just as important as any facet of the game. That's like saying the gameplay isn't Halo or the visuals aren't Halo. It's important to remain consistent. As I said earlier, if it was a Mass Effect trailer I would be completely fine with it, but the first time I heard Marty's ODST score, I literally got shivers and goosebumps down my spine. You could tell it was familiar but different. Even though it was more noire and jazzy, it was still recognizable as Halo music. This was nothing like that feeling, I felt nothing.
