Songfacts®:

• Lopez and her producer, Cory Rooney, thought the album was finished when Sony Music chairman Tommy Mottola and Epic executive Dave McPherson had the idea for one more track called "All I Have." Written by McPherson and Bad Boy songwriter Makeba Riddick, the breakup ballad follows a woman determined to leave a relationship despite her boyfriend's protests. LL Cool J joins Lopez on the duet, which ends up being his first #1 hit on the Hot 100.
• The original idea was for Lopez to cover the 1981 Debra Laws hit "Very Special," but McPherson decided to sample the tune instead, bringing in producer Ron G to mix the track. Laws filed fruitless lawsuits against Sony Music Entertainment for "misappropriating her voice" and copyright holder Elektra Entertainment Group for allowing permission to use the sample without her consent.
• The original title was "I'm Good," a phrase Lopez repeats several times throughout the song.
• This was re-issued on LL Cool J's 2002 album, 10.
• This was featured in the MTV series Undressed in the 1999 episode "The Wrapper and the Rapper."
• This was the first hit song written by Makeba Riddick, who has gone on to craft tunes hits for such A-list stars as Mariah Carey, Beyoncé and Rihanna. Riddick was fresh out of college and had just moved to New York, when the then-president at Epic, having heard her demos asked the young songwriter to write a hit record for Jennifer Lopez. She came up with "All I Have" with the help of her friend Curtis Richardson. Epic executive Dave McPherson loved what she'd written and sent it to Lopez's producer Cory Rooney, who played it to Jennifer Lopez. Rooney then called Riddick up and asked her to come up to the Hit Factory because J. Lo wanted to record it as a single.
