title: Music Genre API?
body: <p>Does anyone know of any Music APIs that let you query with a song name, and return a genre? </p>
  
  <p>i.e. <code>http://foo.bar/api/?song=Baby&amp;artist=Justin+Bieber</code> and have the return be 'Pop'?</p>
  
  <p>I'm making an app that relies on the sole interesting feature being Prediction, yet I need the Genre to determine some extra data!</p>
