The songs appear, but not in list format

Hi! I was working along with the instructor but I can't figure out what went wrong. The list of songs is supposed to appear as an unordered list. What I get is the songs in the same line, separated by commas. The console doesn't mark anything out of order and I can't seem to identify the problem.

var playlist = [
    "I Did It My Way",
    "Respect",
    "Imagine",
    "Born to Run",
    "Louie Louie",
    "Maybellene"
];

function print(message) {
    document.write(message);
}

function printList(list) {
    var listHTML = "<ol>";
    for (var i = 0; i < list.length; i += 1) {
        listHTML += "<li>" + list[i] + "</li>";
    }
    listHTML += "</ol>";
    print(listHTML);
}

print(playlist);

Thanks in advance!

Here's my JavaScript that did the job

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

function print(message) {
  document.write(message);
}

function printList( list ) {
  var listHTML = '<ol>';
  for (var i = 0; i < list.length; i += 1) {
    listHTML += '<li>' + list[i] + '</li>';
  }
  listHTML += '</ol>'
  print(listHTML);
}

printList(playList);

I figured it out. You need to call printList, otherwise all the HTML functionality doesn't apply to your playlist since print(message) just prints your list to the document.
