My vote is for New Order. "Don't Stop Me Now" is a great song, and Queen is pretty underrated around here, but there's only 1 Queen song that can compete with the masterpiece that is "Blue Monday", and it's not "Don't Stop Me Now".
My favorite Queen song beats my 3rd (4th ?) favorite New Order song. Not sure if Temptation or Crystal would have had my vote either, but it would have been much closer.
