title: strange response from spotify api using node js
body: <p>I am creating  a command line app using nodejs. For some reason whenever I enter a track (node liri.js spotify-this-song "enter track") i get a response of a random band called Nocturnal rites, song named "something undefined", and album called "grand illusion". Does anyone know where I am wrong, or why I am getting these responses? </p>
  
  <pre><code>  function spotifyIt(song) {
    spotify.search({ type: 'track', query: song }, function(err, data) {
      if ( err ) {
          console.log('Error occurred: ' + err);
          return;  //from spotify npm docs
      }
      else{
      var songInfo = data.tracks.items[0];
      var songResult = console.log(songInfo.artists[0].name)
                       console.log(songInfo.name)
                       console.log(songInfo.album.name)
                       console.log(songInfo.preview_url)
      console.log(songResult);
      };
    });
  }  
  </code></pre>
