Just a simple mistake in function name. Did you try opening the console? These kind of errors are easy to spot in the console.

var playList = [
  'I Did It My Way',
  'Respect',
  'Imagine',
  'Born to Run',
  'Louie Louie',
  'Maybellene'
];
document.write(playList);

function print(message) {
  document.write(message);
}
// the following function should obviously be named 'printList' (playList is already taken anyway)
function playList(list) { 
var listHTML = '<ol>';
  for (var i = 0; i < list.length; i+=1) {
    listHTML += '<li>' + list[i] + '</li>';

  }
  listHTML += '</ol>';
    print(listHTML);
  }
printList(playList); //now you are calling a function that is not defined (see above, you named that function 'playList'
