And it wasn't just the players singing with fans brilliantly in full voice, too.
The World Cup has got off to a great start, with some very unpredictable results coming our way in Russian Federation.
The passion exuded from Panama's national anthem sent social media into overdrive.
Sweden began the fifth day of the World Cup with an uneventful 1-0 win against South Korea, before Belgium eased past a tenacious, but mostly very bad Panama team.

Panama almost pulled one goal back after a long-range strike from the centre of the pitch rushed Courtois to track back to push the ball to safety in the dying minutes of the extra minutes of the second half. Captain Kane had both of England's goals, his first in a major tournament, and he showed the kind of poise that might have been lacking in some previous England teams on the big stage.
"Now we already know what it's like to play in the World Cup", Gabriel Gomez said.
"Last week Belgium, together with Germany, was chosen for the European group to serve on the UN Security Council in 2019-2020, a challenge that we will take on eagerly".
