Of course as dealer, your vision gets distorted by material you focus on, and your location.
For me most best selling stuff is from Finland, Sweden, Denmark.
Styles most often tape noise, rough edged physical noise. Raw power electronics.
If some years ago, one could move as much Japanese noise as one could stock, now it's entirely different thing. Stocking new release of major japanese artist is less likely sell than debut tape of new project.
At some point german heavy electronics would sell everything. Immediately. Or the Cold Meat kind of stuff. At some point the new wave of USA was hot and discussed by both lovers & haters.
Few years ago the Ramleh, Whitehouse, SJ and CE kind of power electronics appeared to be on utmost rising popularity. Then few years later Cargo is throwing out remains of WH vinyl at almost manufacturing price just to get rid of them and some of the names don't appear to be able to sell out relatively small editions.
But as said, I'm quite sure that what sells good for me, doesn't sell at all from many international distributors. However, I think there is small indication of "popularity", if some bands can move album on tape/LP/CD of hundreds of copies, and others don't think the batch consisting bunch of ltd 15 copies tapes doesn't have enough demand.
So for some artists, noise appears "dead", as most people felt the momentum has passed. And they'll probably fade out, just to wait for next peak in interest and nostalgia fueled reissue offers. Some people don't care of this. They'll keep going regardless. And it's possible that because of this quality, they remain somewhat fresh. No need to have some sort of trend of zeitgeist that is favorable for them and their style.
