NBA and NHL teams blared the recording during games. (Siegel says it was introduced by an executive in the school's athletic department who had heard fans singing it during Italy's championship run.) From there, other universities picked it up. Within a year, the song had made its way from European soccer to American football, starting with fans of Penn State's Nittany Lions. "At that point, it sort of becomes the anthem of the Italian national team - and Italy wins the World Cup," Siegel says. That summer, Italian fans made the "Seven Nation Army" riff their own in the run-up to the 2006 World Cup, where they would score again. Roma, and the tables turned the other way: The Romans headed home with a 2-1 victory - and a brand-new stadium anthem that they'd learned from the Belgians. Three years later, Club Brugge played host to another Italian team, A.S.

"And then Brugge, which is not a traditional power, ended up upsetting Milan." The Belgians sang the riff as their team eked out a 1-0 victory, then brought it home as an unofficial club anthem. "Some supporter groups were having some drinks before the match, and 'Seven Nation Army' was playing," Siegel says. Its life as a sports anthem began six months later, when fans of the Belgian soccer team Club Brugge KV traveled to Italy for a UEFA Champions League match against one of the giants of European football, A.C. 76 on the Billboard Hot 100 after its release in March 2003 (though it did top the Alternative Songs chart). "Seven Nation Army" didn't catch on right away: The song only made it to No. The riff has been deracinated and transformed into this instantly translatable chant.
