Hi Dave,
I haven't reviewed metaflac to see whether its algorithm might incorrectly
show a tag twice. It's possible that dBpoweramp appended a tag that already
existed. I imagine that if metaflac says there's an occurrence of the tag
with no value, and another with a value, then that's probably accurate. Can
you show the output of metaflac? That might help verify.
You could use other tools, like "hexdump -C path/filename" although it
seems that you're on Windows, so you might not have that. Anyway, hexdump
would show the raw file data, and then you could search for the 4-character tag
to see whether it actually appears once or twice in the file.
I'd be tempted to write a simple tool that only shows FLAC chunks as tag and
size, but it's probably quicker to review metaflac to see whether it is
correct.

these with dBpoweramp and this tag was added/defined as a "custom"
tag.

metaflac would be the better tool since it is the "official" tool, at
least I assume it is. Exiftool will read flac files but will not write to them,
so I wonder if I am getting a complete list from it. And MP3Tag has me
wondering, because of the name. I dont care ? OR WANT ? mp3 tags. I only want
FLAC tags.
