I use Navidrome + audinaut as my android app (I only just checked to find out that development on audinaut stopped 4 YEARS ago), so will be looking at this thread for new suggestions…
Have been using easytag on linux and kid3 on mac (kde app - not sure what other free ones there are there) for adding trackinfo so far anyway




Ok you’ve inspired me to get off my butt and set this up on my old S Laptop. Looks like it is in the supported list.
