The above works (I tested it) but I think this is more Rubyish:

<table>
  <tr>
    <th>Songs</th>
  </tr>
  <% if song_list.empty? %>
    <tr>
      <td>no songs!</td>
    </tr>
  <% else song_list.each do |song|%>
      <tr>
        <td><%= song.name %></td>
      </tr>
    <% end %>
  <% end %>
  </tr>
</table>

i.e. get rid of the for entirely.
