Fwd: cannot set COMPOSER

[Bruce Culbertson]

Hello Michael,

Thanks for your e-mail.  I tried something close to your code.  Your code
does not compile but the following does (t is a pointer to Tag):

            TagLib::StringList valList ("Beethoven");
            TagLib::PropertyMap pmap = t->properties();
            pmap ["COMPOSER"] = valList;
            t->setProperties (pmap);
            f->save();

I ran the above code on mp3, flac, and m4a files and it did not change or
insert a COMPOSER tag, it just silently failed to do what I wanted.
However, the following did change the TITLE tag:

            TagLib::StringList valList ("Beethoven");
            TagLib::PropertyMap pmap = t->properties();
            pmap ["TITLE"] = valList;
            t->setProperties (pmap);
            f->save();

So my conclusion is that the creators of taglib just never finished the
code to insert and edit any but the five or six most common tags.

Cheers,
Bruce
