I like the lack of music too, it adds to the "something is off" vibe to this whole thing so far. Like you want it to feel like familiar Twin Peaks, and Lynch drops in just enough but it's never quite enough to scratch that itch. I still think it's building toward that, and I think it'll have more music as it goes. But this story so far is disconnected from the town and is showing how the influence of the Lodge is happening elsewhere, and because of that, and the fact that we haven't been in Twin Peaks proper, I don't think it should feel like Twin Peaks proper.
The lack of music is a major contributor feeling that lack of Twin Peaks quirk, but maybe Lynch wants to branch out (evolve?) into something else/different first. I think when/if the story goes back to the town, and paths begin to cross more back there, that we'll start getting more of that quirk back. If this is his true intention, it's goddamned brilliant.
