Music CD Data

Limbic~Region has asked for the wisdom of the Perl Monks concerning the following question:

All,
I am taking a break from Perl6 to help solve a problem for a relative. They have a huge library of music CDs and find it difficult to remember what they already have when looking to buy new stuff. I was hoping there was something equivalent to ISBN for books so that I could automate most of the process of building a database. Using the UPC, I was able to come up with the following very rough proof of concept:

#!/usr/bin/perl
use strict;
use warnings;
use WWW::Mechanize;
use HTML::Strip;
use HTML::TableContentParser;

my $upc = $ARGV[0] || die 'UPC required';

my $url= "http://www.amusicarea.com/detail/$upc.html";
my $mech = WWW::Mechanize->new( autocheck => 1 );
$mech->get($url);

my %meta;

my $table = HTML::TableContentParser->new()->parse($mech->content);
my $data = HTML::Strip->new()->parse($table->[7]{rows}[0]{cells}[1]{da
+ta});
$data =~ s/\n\s+//;
for my $detail ( split /\n/, $data ) {
    my ($cat, $info) = split /\s*:\s*/, $detail, 2;
    $meta{$cat} = $info;
}

my $song = join '', map {
        HTML::Strip->new()->parse($_->{data})
    } @{$table->[9]{rows}[0]{cells}};
$song =~ s/\n\s*/ /g;
push @{$meta{track}}, $_ for grep $_, split /\s+\d+\.\s+/, $song;

use Data::Dumper;
print Dumper( \%meta );

Before I invest any time into this, I was wondering if anyone else was familiar with a better pre-existing wheel? I spent 2 minutes looking at Net::Amazon::UPC, but I couldn't find any info on the CD in my hand with it. Perhaps I just don't know how to use the module as it seems to me that this is a problem someone else would have already solved. If not, I would be happy to put some real development time into and share it publicly. Your thoughts?

Cheers - L~R
