OK so back on track now
ohw0w I'm glad you found the tune you were lookin for, I was gonna say "Jessica" right away too after reading your description but MikeyChalupa beat me to the punch!
So now I'm tryin to remember what this original tune is, that Jennifer Lopez sampled in the intro to Jenny From the Block:
Children grow and
Women Produce and
Some go workin
Some go stealin
Ev'ryone's got to make a livin...
IT'S KILLIN ME!!! I gotta get that tune out of my damn head!!!!! This is a bad guess but I'm thinkin it's Marvin Gaye or Al Green, or the Isley Brothers but probably not. I think maybe Diana Ross used it at some point too. It's been sampled a few times.
Can anyone help me out here???
