On the Black Star album, Mos Def & Talib Kweli Are Black Star, there is an interlude called "Yo Yeah" that has a collection of several phrases and poems from other people. A Reddit user has identified the poem at the end of the song as "One-Eyed Critics" by Norman Jordan. It was sampled from a recitation of the poem at the Apollo Theater, which was then placed on Black Spirits: Festival of New Black Poets in America. Apparently, it seems as though Jordan was not only uncredited, he never received royalties either.
While this investigative information might be useful to some, it still pales in comparison to the greatest hip-hop mystery revealed: the bass line of Mobb Deep's "Shook Ones pt. 2."
