Archaic Radio on "Randomize Custom Fields from Posts"

Hi Ya'll,

I'm having a hard time getting my page to display a random list of custom fields from a specific post. Below is my code.

<?php
$digvaud_id = 1833;
$digvaud_post = get_post($args,$digvaud_id);
?>

<?php $itemnamefeat = get_post_meta ($digvaud_post->ID, 'wpcf-playlist-song-title', false); ?>
<?php $itemmp3feat = get_post_meta ($digvaud_post->ID, 'wpcf-playlist-song-mp3', false); ?>
<h3 class="playlist-title">Playlist</h3>
<ul>
<?php foreach (array_combine($itemnamefeat, $itemmp3feat) as $itemnamefeat => $itemmp3feat){

$playlist_combinedfeat = '<li><a href="' .$itemmp3feat. '">' .$itemnamefeat. '</a></li>';

echo apply_filters('the_content', $playlist_combinedfeat);
} ?>
</ul>

The result is currently a list of custom field values from post #1833. The only issue I'm having is randomizing the list. Thanks for any help.
