ALBUMARTIST via tag.properties() question

Thank you.
So turns out that if you get the property map like I did in the sample code I had in my msg,
TagLib::FileRef f(filename, false);
TagLib::Tag *t=f.tag();
auto props = t->properties();
that the property map isn’t completely filled out - just has the basic stuff.
But if you get the property map as:
TagLib::FileRef f(filename, false);
auto props = f.file()->properties();
Then the property list is fully populated with all tags as well as the unsupporrtedData() filled in. Just what I need. I discovered this after (belatedly) looking at the example code. I don’t get why the properties from the Tag shouldn’t have worked though - and the FileRef file() member is documented as being something you probably shouldn’t use, so surprises me. But it works and its in the examples, so I’m running with it :)
