Does Kendrick Lamar Actually Sell Better in L.A.?

Previously, the highest charting album with "pimp" somewhere in its title was Pimp C's Pimpalation, which topped out at No. 3 in 2006. Other notable high-ranking "pimp" sets: Too $hort's Shorty the Pimp (No. 6 in 1992), JT Money's Pimpin On Wax (No. 28 in 1999) and Dirty's Keep It Pimp & Gangsta (No. 63 in 2003).

As for the other unique word in Lamar's album title, "butterfly," this is the third go-around for the insect at No. 1. Previous to Lamar, we had No. 1s from Mariah Carey's Butterfly and Bob Carlisle's Butterfly Kisses (Shades of Grace) — both in 1997.
