Bohemian Rhapsody. Because it’s a great song, and because people voting against something because it’s overplayed is silly. It’s overplayed because it’s fantastic.
I still can’t decide on my own, so it’s time to resort to BDMM. (That’s Binary Decision-Making Machine to you.)
Bohemian Rhaphsody.
I haven’t voted as I’ve never heard '39, but can I be the first to point out that it has taken 39 days, 8 threads, and 135 posts to tell us what we already knew from every pop music TV program ever made? 
Final score
Bohemian Rhapsody-11
'39-8.
Thanks for playing.
