DESCRIPTION ^

song(), artist(), album(), year(), comment(), track(), genre()
  $artist  = $id3v1->artist;
  $artist  = $id3v1->artist($artist);
  $album   = $id3v1->album;
  $album   = $id3v1->album($album);
  $year    = $id3v1->year;
  $year    = $id3v1->year($year);
  $comment = $id3v1->comment;
  $comment = $id3v1->comment($comment);
  $track   = $id3v1->track;
  $track   = $id3v1->track($track);
  $genre   = $id3v1->genre;
  $genre   = $id3v1->genre($genre);

Use these functions to retrieve the date of these fields, or to set the data.

$genre can be a string with the name of the genre, or a number describing the genre.

all()
  @tagdata = $id3v1->all;
  @tagdata = $id3v1->all($song, $artist, $album, $year, $comment, $track, $genre);

Returns all information of the tag in a list. You can use this sub also to set the data of the complete tag.

The order of the data is always song, artist, album, year, comment, track, and genre. genre has to be a string with the name of the genre, or a number identifying the genre.

write_tag()
  $id3v1->write_tag();

  [old name: writeTag() . The old name is still available, but you should use the new name]

Writes the ID3v1 tag to the file.

remove_tag()
  $id3v1->remove_tag();

  [old name: removeTag() . The old name is still available, but you should use the new name]

Removes the ID3v1 tag from the file.

genres()
  @allgenres = $id3v1->genres;
  $genreName = $id3v1->genres($genreID);
  $genreID   = $id3v1->genres($genreName);  

Returns a list of all genres, or the according name or id to a given id or name.

new()
  $id3v1 = MP3::Tag::ID3v1->new($mp3fileobj[, $create]);

Generally called from MP3::Tag, because a $mp3fileobj is needed. If $create is true, a new tag is created. Otherwise undef is returned, if now ID3v1 tag is found in the $mp3obj.

Please use

   $mp3 = MP3::Tag->new($filename);
   $id3v1 = $mp3->new_tag($filename);

instead of using this function directly
