Refactoring

[tonylomax]

Your code is pretty neat, if you have time I would start thinking of ways to make it even better. For example, could you write a function that does the below?

trackInfo.id = trackList[randomIndex].track.track_id;
            trackInfo.artist = trackList[randomIndex].track.artist_name;
            trackInfo.track = trackList[randomIndex].track.track_name;
