Lyrics from Snippet:

[Pre-Chorus: Jennifer Lopez]
This is the rhythm, rhythm, rhythm, rhythm
This is the rhythm, rhythm, rhythm, rhythm, rhythm, rhythm
This is the rhythm, rhythm, rhythm, rhythm, rhythm of the night

[Chorus: will.i.am & Jennifer Lopez]
Tonight's gonna be bueno (The night)
I'm talking no problemo (Oh, yeah)
We party to the extremo, baby
(This is the rhythm of the night)
Baby, tonight's like fuego (The night)
We 'bout to spend the dinero (Oh, yeah)
