I have noticed that MP3 songs purchased from Amazon all have a rogue tag for ReplayGain. I thought I had found a way to get rid of them, since they only showed in dBpoweramp, and in no other tag editor. I converted hundreds of files from MP3 to FLAC, then back to MP3, and the rogue tag disappeared from dBpoweramp. It does show in MP3Diags, and now I found another tag viewer called Axone that also shows it. Attached are three screen captures, two from Axone and a third from MP3Diags.
Is there some way to use a script for a new column that will show this tag? It is not one of the the normal ReplayGain tags.
Note that in the second Axone screen, there is a checkbox for "Tag alter preserv." and File alter preserv." I assume that these mean that I am unable to delete the tag. I have tried, but I am unable to uncheck the two boxes.
I'm okay to simply leave it alone, but it does seem to be kind of curious.
