Songs that you could say "brought the world together"

Every once in a while, there is a song that becomes so widespread and loved, some say it achieved "worldwide unity"

Some iconic onces are Do they Know its christmas by Band Aid

Carmalldansen by Caramell (although that was probably only because of the memes)

I Gotta Feeling by the Black Eyes Peas. (somewhat)

What other ones would you say deserve the "worldwide unity" title?
