I am using Mp3tag v2.49a with Creative Labs MediaSource 5 v5.26.02 as my primary player/organizer.
Within MediaSource you can "Edit Track Properties..." via right-click on items in the "Now Playing" list. This brings up a Properties menu. Under the "Tag Information" tab are 11 fields. Ten are standard to ID3 v2.3 (I can verify them with Mp3tag). However, there is a "Custom" field which I am unable to determine its mapping.
I've tried the included tag fields and extended tag fields from the FAQ:
and also a couple guesses at which field this "Custom" is by adding some from the Mp3tag mapping list:
but to no avail. I did not try them all.
Is there an easy way to look at all fields of a file with contents? Or, get a list of what fields a file has (even without contents, I don't mind looking through all of them - but I do mind looking at every field in the entire ID3 v2.3 standard one-by-one manually adding them all into Mp3tag). There has got to be an easy way to find this field and hope someone more experienced and knowledgeable than I can help me out.
If you need to access the app, it can be obtained from Creative here:
Many Thanks in advance!
