Rap songs

I cannot think of a rap song, probably from the 90s, but perhaps from the 80s, that has a chorus composed of samples which includes some scratching. It was a hit song, but not a huge hit. I believe the main beat of the song is with a piano. It has a steady beat like counting numbers. I don’t remember too many lyrics clearly. Within the chorus, there’s a part like “here’s a…” but I know at the end of the chorus someone says “word up,” again from a sample. That part may be from Mos Def, but not sure. The song itself is not by Mos Def (a la Big Brother Beat) At the end of the song, the chorus is played twice. The end of the song the piano plays one two space one, like the end of the horns in EWF’s In the Stone. My guess is this is a solo artist, but I’m not sure.

I don’t remember anything else outside the chorus. I used to hear it regularly when I played Pandora several years ago, but haven’t come across it when I re-engaged.
