Chile's players and fans had to compete with the music of rapper Pitbull, as it was played over the final bars of their national anthem before a Copa America match against Argentina.
It was the second time in two days that the country's national anthem was subject to a mix-up at the tournament.
Organisers apologised for playing the Chile anthem instead of Uruguay before their game against Mexico on Sunday.
Chile went on to lose Monday's game 2-1 to the 2014 World Cup finalists.

American Pitbull has sold more than 60 million records globally - leading to his nickname 'Mr Worldwide'.
