Never mind, I found out how to do it correctly.

I'm sure everyone else probably knows but in case anyone else had
trouble figuring it out like I did, it turned out to be relatively
easy:
TextIdentificationFrame::setText() takes a TagLib::StringList as an
argument which will set the field values.  All that's needed is to
convert QStringList to a TagLib::StringList, get the
TextIdentificationFrame for genre ("TCON") and call setText with the
new TagLib::StringList.  Reading it back is just the
TextIdentificationFrame::fieldList().

Thanks again for all your hard work on taglib.
