Is there a way I can easily remove all instances from every tag contains the characters "PMEDIA"? For example, a typical mp3 I obtained has PMEDIA in many of the typically unseen tags like ISRC, Uploader, and release country. I also would like to remove all of the instances of tags that contain the expression pmedia, but are not limited to just those letters. An example would be this odd expression
eng||www.t.me/pmedia_music which is found in the very odd unsynchedlyrics field. Just out of curiosity, what do the two upward bars (which is found with the backward slash key) do? Seems suspicious to me.
@joeleger This would remove all the selected tags from all your selected tracks. Not only the ones with PMEDIA inside a specific tag.
You need to find the tracks with the tag containing PMEDIA first. Then you can use your steps.
Otherwise you delete content from tags that you want to keep (content that could be something else then PMEDIA).
As @ohrenkino wrote more then 10 years ago in the above linked thread, please use a Filter (F3) first:
and enter PMEDIA to show only tracks with PMEDIA somewhere in your tags.
