Sounds like Black Sheep - The Choice Is Yours. I never really listened to rap, but my girl- friend at the time, who was seven years younger than me, was caught up in that phase. She used to sing that song a lot when it came out...it was one of her favorites. She gradually out grew that phase. One time I let it rub off on me, and went to my job when I was a guard, singing verses to that song...and the fellas looked at me like I was a fool. That was the first and last time I went to work singing rap.
Anyway, to me that part of the song you mentioned above have a similar beat.
