Thanks everyone for the replies.

CountZero that code is just what I was looking for!

I should have explained my self a bit more. I'm learning Perl and havn't been using it much, so at the moment I'm just playing around, seeing what it can do.

If I download the first part of an mp3 file chances are it will have the tag in (well, so far anyway) which I can read and see what the file contains - if the name isn't self-explanatory. So, an entirely useless script but I wanted to see if it could be done ;-)

Here the final script if anyones interested. I think it needs a lot of cleaning up >.<

Does the -w in the shebang line and the 'use warnings' mean the same thing? And what are things like the '-w' called (eg the -f or -d to specify file or directory)? Google doesn't like searching for one-letter things which makes it nearly impossible for me to find out!

#!/usr/bin/perl -w
use strict;
use warnings;
use MP3::Tag;
use LWP::UserAgent;

my $dir = "./";
my $ua = LWP::UserAgent->new();
my $url = ""; ## <<< url to get files from
my $buffer;

my @files;
my $response = $ua->get($url);
if($response->is_success){
    my $con = $response->content;
    while ($con =~ /<a href=\"(.*?)\.mp3\">/g){
        push @files, "$1.mp3";
    }
}

foreach my $file(@files) {
    print "Reading $file...";
    $ua->get($url.$file, ':content_cb' => \&first_chunk, ':read_size_h
+int' => 10240 );
    
    sub first_chunk {
    my ($chunk, $response_ref, $protocol_ref) = @_;
    $buffer .= $chunk;
    die() if length($buffer) >= 10240;
    }
    
    ## Clean filename
    $file =~ tr/+/ /;
    $file =~ s/%([a-fA-F0-9]{2,2})/chr(hex($1))/eg;
    $file =~ s/<!--(.|\n)*-->//g;
    
    ## Save file
    open FILE, ">$file", or die $!;
    print FILE $buffer;
    close FILE;
    print " Done!\n";
    
    ## Clear buffer
    $buffer = "";
    
    ## Find tags
    my $filename = "$dir$file";
    my $mp3 = MP3::Tag->new($filename);
    my ($song, $track, $artist, $album) = $mp3->autoinfo();

    ## Print tag: Artist - Album (if any) - Song
    unless ($album) {
        if ($artist) {
            $album = " - ";
        }
    } else {
        $album = " - $album - ";
    }
    print "$artist$album$song\n";
}
