The melody is FC Barcelona's club anthem, a song closely associated with the Catalan club and sung by supporters at home matches for decades. Brazilian broadcaster Globo has long carried major football coverage in Brazil, which is why versions labelled for its broadcasts circulate among Portuguese-speaking fans online. Short clips like this one are shared in fan edits, goal compilations and social posts, where the instantly recognisable tune works as shorthand for Barça pride. Its continued use comes from that strong club identity rather than any single viral moment.
