hi,

you have:

function Media(title, artist, duration) {
  this.title = title; 
  this.duration = duration;
  this.isPlaying = false;
}

while it should be:

function Media(title, duration) {
  this.title = title; 
  this.duration = duration;
  this.isPlaying = false;
}

as you define artist in constructor of an extended object. Cheers!
