title: Python: decode mp3
body: <p>I need to decode an MP3 file with Python. What is a good library which can do that?</p>
  
  <p>I looked at PyMedia but the project seems dead and it didn't worked on MacOSX. Then I found out about pyffmpeg but I didn't got it working on MacOSX so far.</p>
  
  <p>Any suggestion?</p>
