tis is not correct. htmlString += 'class="current"';

and should be space between single quot and class, like this.

htmlString += ' class="current"';

You made two mistakes:

  1. in the constructor function of playlist you wrote "this.song"(singular), but in the add function you wrote "this.songs"(plural).
  2. in the add function you don't have a parameter. Always remember to check the javsacript console , it will help you a lot when debugging some code.
