In the renderInElement when you are looping through this.songs.length and add to the list.innerHTML, after this.songs[i].toHTML you should have an opening and closing parentheses, since it is calling the toHTML method inside of songs.js

And please elaborate a bit on the nature of the issue. "This won't work" is a bit vague.
