MP3 Year / Date

[samhnky]

Is anyone able to provide guidance on how to add the ID3 Year/Date tag? http://wheelersburgfaithbaptistchurch.com/connect/sermon-audio

I added the following code to the following file: content/mp3browser/html/HtmlNameColumn.php

   protected function getCellText($data, $isAlternate) {
        $html = $this->addItemAnchor($data);
        if ($data->getTitle()) {
            $title = $this->wrapAnchor($data, $data->getTitle());
            $html .= "<span style='font-size: .7em;'>Message Title:</span><strong>" . $title . "</strong>";
        }
        if ($data->getArtist()) {
            $artist = $this->wrapAnchor($data, $data->getArtist());
            $html .= "<br/><span style='font-size: .7em;'>Speaker:</span>" . $artist;
        }
         if ($data->getDate()) {
            $date = $this->wrapAnchor($data, $data->getDate());
            $html .= "<br/><span style='font-size: .7em;'>Date:</span>" . $date;
        }
        return $html;
    }

If I use $date I do not get an error, if I use Year I get an error,..
