Insert shortcode before and after a list automatically

Question

I'm setting up a custom page template and I'm building a widget on it that lists albums with track lists. I use a plugin that allows me to expand text which is what I use to show tracks of the albums on click. My problem is adding the information for different artists each time. The idea is to set up the widget on the page template and then enter the guts lists items into a custom field and then calling it into the widget. The problem for me is using the shortcode from the plugin that's used inside the list items. So what I'd like to do is automatically include the shortcode before and after the child ul of a list item. I'm sure that made no sense so here's the setup.

code on page template...

<div class="albums">
    <h2 class="artist-widget">Albums</h2>
        <ul>
          <?php echo $albums; ?>
        </ul>
</div>

heres what I call in the custom field minus the shortcode that I need to insert automatically...

<li><div class="cover"><img src="" /></div><h3>header..</h3>
  [DDET see track list]
     <ol>
       <li>Intro (Album Version) 00:06</li>
       <li>What Up Gangsta [Album Version (Edited) 02:57</li>
       <li>Intro (Album Version) 00:06</li>
       <li>Intro (Album Version) 00:06</li>
     </ol>
  [/DDET]
</li>
<li><div class="cover"><img src="" /></div><h3>header..</h3>
  [DDET see track list]
     <ol>
       <li>Intro (Album Version) 00:06</li>
       <li>What Up Gangsta [Album Version (Edited) 02:57</li>
       <li>Intro (Album Version) 00:06</li>
       <li>Intro (Album Version) 00:06</li>
     </ol>
  [/DDET]
</li>

How can I get the [DDET][/DDET] in there with a function?

While I'm not completely sure what you're trying to accomplish, you can use the following to programatically use a shortcode:

echo do_shortcode('[DDET]Content goes here[/DDET]');
