NAME

Music::Tag::MP3 - Plugin module for Music::Tag to get information from id3 tags

SYNOPSIS

	use Music::Tag

	my $info = Music::Tag->new($filename, { quiet => 1 }, "MP3");
	$info->get_tag();
   
	print "Artist is ", $info->artist;

DESCRIPTION

Music::Tag::MP3 is used to read id3 tag information. It uses MP3::Tag to read id3v2 and id3 tags from mp3 files. As such, it's limitations are the same as MP3::Tag. It does not write id3v2.4 tags, causing it to have some trouble with unicode.

REQUIRED DATA VALUES

No values are required (except filename, which is usually provided on object creation).

SET DATA VALUES

mp3 file info added:

Currently this includes bitrate, duration, frequency, stereo, bytes, codec, frames, vbr, 

auto tag info added:

title, artist, album, track, comment, year, genre, track, totaltracks, disc, totaldiscs, composer, and performer

id3v2 tag info added:

label, releasedate, lyrics (using USLT), encoder (using TFLT), and picture (using apic).

The following information is gathered from the ID3v2 tag using custom tags

TXXX[ASIN] asin =item TXXX[Sortname] sortname =item TXXX[MusicBrainz Album Artist Sortname] albumartist_sortname =item TXXX[MusicBrainz Album Artist] albumartist =item TXXX[ALBUMARTISTSORT] albumartist =item TXXX[MusicBrainz Album Release Country] countrycode =item TXXX[MusicBrainz Artist Id] mb_artistid =item TXXX[MusicBrainz Album Id] mb_albumid =item TXXX[MusicBrainz Album Status] album_type =item TXXX[MusicBrainz Artist Type] artist_type =item TXXX[MusicIP PUID] mip_puid =item TXXX[Artist Begins] artist_start =item TXXX[Artist Ends] artist_end =item TXXX[EAN/UPC] ean =item TXXX[MusicMagic Data] mip_puid =item TXXX[MusicMagic Fingerprint] mip_fingerprint

Some data in the LAME header is obtained from MP3::Info (requires MP3::Info 1.2.3)
