title: Using the genres filter on Soundcloud API
body: <p>I am using the genres filter on Soundcloud API, the codes:</p>
  
  <pre><code>$tracks = $client-&gt;get('tracks', array('genres' =&gt; 'punk'));
  </code></pre>
  
  <p>It is working well and return all tracks which genre are punk, but when I try to change the codes:</p>
  
  <pre><code>$tracks = $client-&gt;get('tracks', array('genres' =&gt; 'rock'));
  </code></pre>
  
  <p>It can not return  all tracks which genre are rock.</p>
  
  <p>My question is: where can we find correct music genres from Soundcloud?</p>
  
  <p>Maybe the Soundcloud API which should give us a method to get a list for common genres.</p>
