iTunes and MP3::Tag

Near New Year I visited some friends, so got an access to iTunes.
Unfortunately, I could not find way to make iTunes recognize anyway
non-trivial tags (darwin iTunes v4 and v6 tried).

While ID3v2.3 specification (one used by MP3::Tag for writing) is not
the easiest reading, I'm pretty sure I exhaused different ways to
interpret it.

Catching the last straw: could any one please check whether one of

ilyaz.org/software/tmp/empty1.mp3
ilyaz.org/software/tmp/empty2.mp3

shows author/title tags in ITunes? It should be "a with (..)" "t with
(..)" correspondingly, here .. is y-diaresis eth:

.. |
\ / |O
| |

(picture assumes fixed-width fonts).

Thanks,
Ilya
