I'd like to considerably reduce the number of genres in my library. I've made most of the cleanup, but that are still a few files that I don't seem to be able to fix. For those few files, my Sonos will list their genre ("other" or "unknown" or "blues"), but when I run mp3tag on those specific files, no tag show up (field empty). However, if I mouse-over the file in Windows, I do see the same genre as the one listed in my Sonos library (I am not sure if Windows is providing the mouse-over info, or if it is DBPowerAmp.. could be either).
I'm guessing that either the tag is broken for this file, or there is a bug in mp3tag that prevents it from reading this file. I have this issue with about 20 files out of 30k....
What would be the appropriate steps to resolve/investigate this? I can share the problematic file if needed.
