Look into File::Find. One of the first things to learn with perl is how to use already existing modules and libraries... no need to reinvent the wheel on this one.

Something like this is what you'd end up with:
use strict;
use File::Find;
use File::Basename;

my($topdir) = '/'; # where you want to start from

my(@files) = find ( \&wanted, "$topdir" );

foreach (@files) {
    my($dir) = dirname($_);
    if ($dir ne $prev_dir) {
        print "<P>" . $dir . "</P>\n";
        $prev_dir = $dir;
    }
    print "<BLOCKQUOTE>" . $_ . "</BLOCKQUOTE>\n";
} 

sub wanted {
    /\.mp3$/ && -f;
}

Update: As Corion so aptly put, my regex was simply wrong. I fixed it. Serves me right for posting untested code.
