The discography of Nas, an American rapper, consists of ten studio albums, three collaborative albums, three compilations, one extended play, and twenty-six singles.
 The son of jazz musician Olu Dara, Nas dropped out of school during ninth grade and began his music career in 1991 with a guest performance on the song "Live at the Barbeque" by Main Source.
 In 1992, Nas contributed the track "Halftime" to the soundtrack to the film "Zebrahead", and Nas was soon signed to Columbia Records and released his debut album "Illmatic" in 1994.
 Including Nas's solo debut track "Halftime", "Illmatic" was certified platinum in the US, spawned several singles including "It Ain't Hard to Tell" and "The World Is Yours", and earned much critical acclaim.
 With a more mainstream-oriented sound, Nas's second album "It Was Written" was released in 1996 and included the Lauryn Hill collaboration "If I Ruled the World (Imagine That)" and "Street Dreams", the latter of which reached number 22 on the "Billboard" Hot 100 chart and number 1 on the Hot Rap Singles chart.
 "It Was Written" was certified quadruple platinum.
 In 1999, Nas released two albums: "I Am…" and "Nastradamus".
 While "I Am" reached double platinum status like its preceding album "It Was Written" and spawned two singles that reached the top ten spots of the Hot Rap Singles chart, "Hate Me Now" and "Nas Is Like", "Nastradamus" signaled a decrease in quality and critical reception and sold only half as many units.
 Still, "Nastradamus" featured two charting singles, "You Owe Me" and "Nastradamus".
