"Watch Out Now" is the first single from A Musical Massacre, a 1999 album by East Coast hip hop group The Beatnuts.
The song is produced by The Beatnuts and features materialistic raps by JuJu and Psycho Les, as well as a chorus performed by Yellaklaw.
A "Watch Out Now" remix produced by Trouble Men was released as a single in France, but did not receive music video treatment as the original version did.
[citation needed] In 2002, Jennifer Lopez released "Jenny from the Block", a single that allegedly stole the Beatnuts' sample of "Hi-Jack" by Enoch Light (a song originally written by Spanish musician Fernando Arbex and was recorded by the group Barrabás for their 1974 album ¡Soltad a Barrabás!).
The Beatnuts expressed their displeasure with Lopez and her producers on the 2004 song "Confused Rappers" as well as through various interviews.
