SYNOPSIS

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

         ($title, $artist, $no, $album, $year) = $mp3->parse_filename();

DESCRIPTION

       MP3::Tag::File is designed to be called from the MP3::Tag module.

       It offers possibilities to read/write data from files via read(), write(), truncate(),
       seek(), tell(), open(), close(); one can find the filename via the filename() method.

       parse_filename()
             ($title, $artist, $no, $album, $year) = $mp3->parse_filename($what, $filename);

           parse_filename() tries to extract information about artist, title, track number, album
           and year from the filename.  (For backward compatibility it may be also called by
           deprecated name read_filename().)

           This is likely to fail for a lot of filenames, especially the album will be often
           wrongly guessed, as the name of the parent directory is taken as album name.

           $what and $filename are optional. $what maybe title, track, artist, album or year. If
           $what is defined parse_filename() will return only this element.

           If $filename is defined this filename will be used and not the real filename which was
           set by MP3::Tag with "MP3::Tag->new($filename)".  Otherwise the actual filename is
           used (subject to configuration variable "decode_encoding_filename").

           Following formats will be hopefully recognized:

           - album name/artist name - song name.mp3

           - album_name/artist_name-song_name.mp3

           - album.name/artist.name_song.name.mp3

           - album name/(artist name) song name.mp3

           - album name/01. artist name - song name.mp3

           - album name/artist name - 01 - song.name.mp3

           If artist or title end in "(NUMBER)" with 4-digit NUMBER, it is considered the year.

       title()
            $title = $mp3->title($filename);

           Returns the title, guessed from the filename. See also parse_filename().  (For
           backward compatibility, can be called by deprecated name song().)

           $filename is optional and will be used instead of the real filename if defined.

       artist()
            $artist = $mp3->artist($filename);

           Returns the artist name, guessed from the filename. See also parse_filename()

           $filename is optional and will be used instead of the real filename if defined.

       track()
            $track = $mp3->track($filename);

           Returns the track number, guessed from the filename. See also parse_filename()

           $filename is optional and will be used instead of the real filename if defined.

       year()
            $year = $mp3->year($filename);

           Returns the year, guessed from the filename. See also parse_filename()

           $filename is optional and will be used instead of the real filename if defined.

       album()
            $album = $mp3->album($filename);

           Returns the album name, guessed from the filename. See also parse_filename() The album
           name is guessed from the parent directory, so it is very likely to fail.

           $filename is optional and will be used instead of the real filename if defined.

       comment()
            $comment = $mp3->comment($filename);   # Always undef

       genre()
            $genre = $mp3->genre($filename);       # Always undef
