HTML5 <nav> Element

Question

I always try to use new html5 elements, but find myself doing things like this:

<nav class="some-menu">
    <ul class="menu">
       <li>
           <a title="link to somewhere" href="the-link.php">link to somewhere</a>
       </li>
    </ul>
</nav>

When I could achieve the same (visually) with:

<ul class="menu">
   <li>
       <a title="link to somewhere" href="the-link.php">link to somewhere</a>
   </li>
</ul>

More simplicity markup and bloated DOM, should the tag be included <nav>in this situation?

EDIT

I found that the element <menu>can be used in this situation along with <li>for example:

<menu class="side-menu">
    <li><a title="a menu item" href="touch-my-nipples.thanks">Inappropriate Href</a>
</menu>

Which gets more meaningful markup without details.
