Answer 1

  //So this is what I found.  This actually involves a few things.
  //FIRST, capture user-input,
  //SECOND, npm install spotify, and use the template as suggested in the DOCS. 
  //THIRD, parse through the JSON correctly as done below.

  //HOPE this helps someone.  (dont forget your keys from spotify)


  var songName = process.argv[3]; //capture userInput and query it below 

 params = songName;
    spotify.search({ type: 'track', query: params }, function(err, data) {
        if ( err ) {
            console.log('Error occurred: ' + err);
            return;  
        }
        else{
            output = space + "================= DATA HERE ==================" + 
            space + "Song Name: " + "'" +songName.toUpperCase()+ "'" +
            space + "Album Name: " + data.tracks.items[0].album.name +
            space + "Artist Name: " + data.tracks.items[0].album.artists[0].name +  
            space + "URL: " + data.tracks.items[0].album.external_urls.spotify + "\n\n\n";
            console.log(output);    
            };
    });
