There are many historical firsts in Billboard chart history, and Kendrick Lamar just notched a pretty unique landmark: "To Pimp a Butterfly" is the first No. 1 album with the word "pimp" in its title.
Billboard.com reports that the last album with "pimp" in the title that charted was Pimp C's "Pimpalation," which hit No. 3 in 2006. The site also notes that "butterfly" is a rare word for a No. 1 album, last seen in Mariah Carey's "Butterfly" and Bob Carlisle's "Butterfly Kisses (Shades of Grace)," both of which came out in 1997.
Released March 16, the acclaimed "To Pimp a Butterfly" is Lamar's first No. 1 album. 2012's "good kid, m.A.A.d city" peaked at No. 2, selling 241,000 copies. "Butterfly" debuted with 363,000 equivalent album units, which represent copies sold as well as individual tracks purchased and streamed via services like Spotify and Google Play. Lamar saw the year's second-highest debut to date, behind Drake's surprise mixtape, "If You’re Reading This It’s Too Late," which sold 495,000.
