what I want to achieve is pretty straightforward but for some reason I can't get it to work! What I want to do is When you click on one of the links to a specific genre I want the correspond list of song titles to display, preferably slide down. Any help would be appreciated. Here's my html so far:

```
<p><a class="rock" href="">ROCK</a> / <a class="blues" href="">BLUES</a></p>

                    <section class="container">
                    <div class="leftcolumn">
                        <ul class="rock">
                            <li>AUTOHAZE</li>
                            <li>BASSHOLES</li>
                            <li>BEAT ANGELS</li>
                            <li>BONFIRE MADIGAN </li>
                            <li>BOOM</li>       
                        </ul>

                        <ul class="blues">
                            <li>20 MILES    </li>
                            <li>AARON MOORE </li>
                            <li>ALBERT AMMONS   </li>
                            <li>ARON BURTON </li>
                            <li>ARTHUR CRUDUP   </li>
                        </ul>
                    </div>
                    </section>

```
