Greensleeves is almost 500 years old. I'm sure there were other very popular songs when it came out, but Greensleeves had to staying power to still be here. What do you think is today's Greensleeves?
One thing people might not realise, is that memorable old music can come and go. Until someone recorded a successful rendition in the 60's, Cannon in D had been forgotten for centuries. Now it's almost synonymous with wedding music, and seems completely timeless.
It's possible everyone will be crazy about 1919's El sombrero de tres picos in 2450, and (with this all being indistinct distant history) will picture us in 2024 playing it on boombox at a 2050's-style holo-orgy.

On a serious note, if anyone's an American who's serious about relocating to Canada and not just memeing, I'd get moving on it now. We have a massive housing shortage, and things would get sticky politically if there was a big wave of people pushing prices up even more.
I think having a dance associated with the song is integral to the staying power of a song. The Twist, Hokey Pokey, Electric Slide, all great contenders.
But time will prove that the champion is The Macarena, by Los Del Rio.
