You could work with array_slice() on the result of the DOM parser... Something like the following code could do the trick (untested code):

<?php 

include('simple_html_dom.php');
$page = array_key_exists('startrow', $_GET) ? (int)$_GET['startrow'] : 1;
$search = $_GET['search']; 
$html = file_get_html('http://mysite/'.$search.'.html');

$songs = $html->find('div#song_html ');
$paginationStart = min((10 * ((int)$page - 1)), (count($songs)-1));

$results = array_slice($songs, $paginationStart, 10);
foreach ( $results as $e ) {
    $title= $e->find('div', 2)->plaintext;
    echo $title.'<br>'; 
}
