TERESOPOLIS, Brazil (AP) — Go ahead, FIFA, stop the music if you want. Fans will keep singing anyway.
FIFA limits anthems to 90 seconds so they can get the World Cup games going quickly. But many national songs last much longer, and the fans — particularly South Americans proud to have the cup in their territory — are loudly taking over with a cappella renditions of the anthems that are bringing tears to the eyes of players.
Unintentionally, FIFA has created some of the most emotional and patriotic moments of the World Cup.
"When we hear the anthem being sung like that, we get extra motivated, there's no doubt about that," Brazil captain Thiago Silva said. "It shows that the fans are with us. It has become part of the national team and that has had a great influence on how we play."
Brazilian fans started doing it last year, and supporters of Chile and Colombia have picked up on the idea.
With no music in the background, hearing tens of thousand fans sing together has caused goose bumps for many in the stadiums and shocked players from opposing teams.
Before both of Chile's World Cup games, fans sang for nearly 30 seconds after FIFA cut off their anthem— the chorus of which says Chile will be the tomb of the free or the refuge against oppression.
"The way they sing the national anthem is impressive, spectacular," Chilean federation president Sergio Jadue said.
Colombian fans put on a spectacle in the match against Greece in Belo Horizonte, loudly belting out "Oh Gloria Inmarcesible!" ("Oh Unfading Glory!") for nearly 30 seconds after FIFA stopped the music inside the packed Mineirao Stadium.
Brazil's anthem normally lasts almost four minutes and has an introduction of nearly 20 seconds before the lyrics start. FIFA said the Brazilian federation provided a 60-second version.
After the music ends, Brazilian players and fans continue singing even louder for nearly half a minute, belting out the lyrics, which include a reference to "the resounding cry of a heroic people." The sing-a-along ignites the crowd and motivates the team.
"The reaction from the fans to the anthem has been amazing," goalkeeper Julio Cesar said after the opener against Croatia in Sao Paulo. "It brings them closer to us and we get closer to them."
Croatia's players appeared surprised when the crowd kept singing. Some looked to the Brazilian players to see what they were doing, but remained in line respectfully.
