This might be obvious to most folks, but I just stumbled upon a little bit of PHP code which allows me to show different Amazon MP3 widgets every time a test page loads -- sure beats JavaScript hassles!
Anyhow, here it is, if it can help anybody else:
<?php
$chunk = array("{{chunk1}}", "{{chunk2}}", "{{chunk3}}");
$randomChunks = $chunk[array_rand($chunk, 1)];
echo $randomChunks;
?>
