Club America was founded in 1916 in Mexico City and is one of Mexico's most successful football clubs, known as Las Aguilas and long associated with Estadio Azteca. Its anthem and chants have become a familiar part of matchdays, television broadcasts and fan videos. Short clips of the melody circulate on soundboards because they are instantly identifiable to supporters and rivals alike. Fans reuse the sound online to mark victories, tease opposing teams and add a stadium atmosphere to short soccer edits and social posts.
