title: Detect Song with Java
body: <p>Is there a library for detecting the currently playing song with Java? Not only with WinAMP or WMP, but generally, a technique to listen the audio output for example? </p>
  
  <p>Thank you. </p>
  
  <p><strong>Edit: No, I just want to listen the audio output and decide whether there's a song playing right now, or not. 
  Not identifying. Just there's a song or not (playing right now).</strong> </p>
