Changing Most Commented Posts To Most READ Posts

I use a tabbed widget that shows Recent, Popular and Random Posts.

The tab for Popular Posts current shows posts with highest number of comments.

I would like to change that to posts with highest number of VIEWS.

Is that possible? The current php script is like this –

<div id=”popular-tabbed” class=”tab”>

<?php global $wpdb;
$result = $wpdb->get_results(“SELECT comment_count,ID,post_title FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , $popularPostsNumber”);
foreach ($result as $post) {
#setup_postdata($post);
$postid = $post->ID;
$title = $post->post_title;
$commentcount = $post->comment_count;
if ($commentcount != 0) { ?>
<?php query_posts(“p=$postid”); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php include(TEMPLATEPATH . ‘/includes/fromblog_post.php’); ?>
<?php endwhile; endif; wp_reset_query(); ?>
<?php };
}; ?>

</div>

Thanks in advance!
