Scrobbling to last.fm from Perl

Here's some Perl that allows you to scrobble directly to your last.fm profile.

First install the following modules. The first pulls tag metadata out of MP3 files, while the second sends the information to last.fm.

http://search.cpan.org/~daniel/MP3-Info-1.23/Info.pm

http://search.cpan.org/~roam/Audio-Scrobbler-0.01/lib/Audio/Scrobbler.pm

(to install these use: perl -MCPAN -e 'shell', then install MP3::Info, and install Audio::Scrobbler)

use MP3::Info;

use Audio::Scrobbler;

my $info = get_mp3info($file);

my $tag = get_mp3tag($file) or die "No TAG info";

my $mp3_title = $tag->{TITLE};

my $mp3_artist = $tag->{ARTIST};

my $mp3_album = $tag->{ALBUM};

my $mp3_length = int($info->{SECS});


$scrob = new Audio::Scrobbler(
cfg => {
progname => "tst",
progver => "1.0",
username => "someone",
password => "somepass",
verbose => "1"
}
);

$scrob->handshake();

$scrob->submit(
{
title => "$mp3_title",
artist => "$mp3_artist",
album => "$mp3_album",
length => "$mp3_length"
}
);
