Post Loop & query_posts()

Hello,

In single.php I’m attempting to list random posts in the current category.

Here’s the code:

if (have_posts()) : while (have_posts()) : the_post(); ?>
<!--The Post Is Here-->
<?php endwhile;
	$similar_posts = single_cat_title("", false);
	query_posts( $similar_posts . '&order=ASC&posts_per_page=10' ); ?>
	<h3>Similar Song Lyrics By This Artist:</h3>
	<?php
	while ( have_posts() ) : the_post();
	echo '<li>'; ?>
	<a href="<?php the_permalink() ?>" rel="bookmark" title="Song lyrics for <?php the_title(); ?>"><?php the_title(); ?></a>
	<?php echo '</li>';
	endwhile; ?><br />
	<?php else: ?>

For some stupid reason it’s not listing the posts from the current posts category. Thanks!
