Wow. Just tried browsing a 200G MicroSD card. Used to be barely workeable. Now very fast. New Genres / Arists browsing is working very well too.
Although, I did get a few times tracks listed in an incorrect order (ex: tracks 2-5 listed first, then track 1). Always with the lowest track number presented last, but the rest in order.
That was in "Artists" views.
