Let's Get Loud

"Let's Get Loud" is a song recorded by American entertainer Jennifer Lopez for her debut studio album On the 6 (1999). Originally written by the song's co-writer Gloria Estefan for herself, she felt as if the song was too similar to her previous material and passed it onto Lopez. Estefan, who co-wrote the song alongside Kike Santander, stated that she would have "more fun with it" and would put "a new spin" on it. "Let's Get Loud" is often regarded as Lopez's signature song.

Since its release, "Let's Get Loud" charted on several charts around the world, reaching the top ten on five European countries. Despite not being released in the United States, it also charted on the US Billboard Hot Dance Club Songs. "Let's Get Loud" received positive critical response and at the 43rd Grammy Awards in 2001, Lopez earned her second consecutive nomination for the Grammy Award for Best Dance Recording with the song. An acompanying music video was directed by Jeffrey Doe and filmed live at the 1999 FIFA Women's World Cup.
