"Let's Get Loud" is a song recorded by American singer 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 Lopez would have "more fun with it" and would put "a new spin" on it. "Let's Get Loud" is sometimes regarded as Lopez's signature song. Estefan eventually released her own version of the song in 2011 as a bonus track on the deluxe Target edition of her album "Miss Little Havana".
