Ignoring the empty links I would start with html that looks like this.
<div class="wrap">
<h1 class="title">Links</h1>
<ul class="nav">
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
</ul>
<audio></audio>

The h1.title assumes this is just the only one on the page otherwise a heading of suitable rank would need to be used.
CSS to follow in a minute:
Of course the JS will also need to be refactored to account for the changes.
