It's a little hard to read in the post, but I think the first issue is that the writeList function is never called against the playlist to generate the HTML output. Try changing the last print(playList) call to writeList(playList).

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

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

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

  listHTML += "</ol>";
  print(listHTML);
}

writeList(playList);

The fix that @Steve Mustanski provided you should give you the ordered list. Note that when speaking of an ordered list given by the <ol> tag, it means a list of items preceded by an ordered numeric or alphabetic identifier, not the list itself.
