This is based on Freddie Scott's 1968 R&B song "(You) Got What I Need," which was written by the Philadelphia songwriting/production team of Kenny Gamble and Leon Huff. Biz used piano medley and the phrasing of the line "You got what I need," but changed the subject matter completely.
Despite the obvious influence, Biz Markie (real name: Marcel Hall) is the only songwriter credited on this track. This was common practice at the time, as most samples and interpolations were not cleared.
On his next album, Markie did a similar interpretation of "Alone Again (Naturally)
" by Gilbert O'Sullivan for the track "Alone Again." At the time, rappers could sample without consequence, as there was no legal precedent. This changed when O'Sullivan sued Biz Markie in 1991, resulting in a landmark decision that unauthorized samples were considered theft. Markie was forced to pull the album and re-issue it without "Alone Again." (thanks, Bertrand - Paris, France)
