My intent is to remove a “custom” tag that inadvertently ended up with a with the space in it’s name (Song Rating) and replace it with a tag with no space (SongRating).</div>

So now the question begs to be asked. If there are 2 tags, or more, with the same name. One with a value and one without, or for that matter they both have values and you want to remove a specific one. How would I do that. If I use the metaflac command:</div>
<div class="elementToProof" style="margin: 0in; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
metaflac --remove-tag=SongRating WorkingMan_Copy.flac</div>
<div class="elementToProof" style="margin: 0in; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
it removes both.</div>

<div style="font-size: 11pt;">Hi Dave,<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>

as a "custom" tag.<br>

> Does anyone know why it might be listed twice using metaflac. I thought 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.<br>
