I filled the metadata of my songs with Picard without any problem, but now for some reason I can no longer modify my tags or my data. I just want to add some tags like my UPC code and my ISNI number but i cant no longer edit my data why? Thx for your help!
Thanks for posting, but I don’t fully understand the issue. Can you be more specific what you mean “i cant no longer edit my data”. Are you trying to edit the tags with Picard, but it does not save it? Or are you using some other tool?
If you use Picard make sure you have Options > Save Tags enabled.
