i normally deal in mp3 and flac, and i don't have many m4a/mp4 files, so i didn't notice this until now.
however, at some point a few winamp versions back i standardized all my files with winamp to a set list of genre tag possible values. np, winamp seemed to do it fine.
so whats the problem you say? everything seems to be as intended...
well, i was doing some routine maint on the collection, so i ran everything thru mp3tag 2.52, and suddenly i notice some strange values in the genres for some of these files. some are correct, meaning what i set, but some are values i don't use, and that DON'T appear in winamp AT ALL.
i do "extended tags" and indeed, i only see what mp3tag reports, not what winamp and other apps report.
so the question is which is wrong? what i can't fathom, is how both apps are divergent, even after specifically told to "refresh" whats displayed?
if it is "multiple frames" why don't i see the winamp values in mp3tags extended tags?
