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?

Not just a song that can be found in the archives, but one that almost everyone can hum, even today.

(Somebody asked what was meant by "today's...." Throw whatever you want out, somebody tossed out "Love me tender" as being a tune from in the 1860s.)
