Sample info pls

[kagenaki koe]

lately i've been hearing this one jungle track that has an old r&b/soul sample, and it was the same one that was used by the rapper Freeway on the song "What We Do" (featuring beanie seigel and jay-z) i think it was one of Kanye West's production.

but anyhow, does anybody know who the original artist/song is?

both the jungle and freeway track contains the line "even though what we do is wrong" repeated throughout both tracks.
