title: How to play a simple song using PyQt's Phonon?
body: <p>I'm trying to play a single mp3 file on my software when a button is pressed.
  Here's how i did it:</p>
  
  <pre><code>QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), playsong)
  </code></pre>
  
  <p>and the function:</p>
  
  <pre><code>def playsong():            
          m_media = Phonon.MediaObject()
          m_media.setCurrentSource(Phonon.MediaSource("files/song.mp3"))
          m_media.play()
  </code></pre>
  
  <p>This doesnt raise any error.
  But the song wont play.
  I've seen a lot of exemples in C++ and some in python which has a lot of songs, and playlist, etc.
  I just want to play a single song, am i missing something?</p>
