Doin' It (LL Cool J song)

"Doin It" is a song by American rapper LL Cool J, released by Def Jam Recordings on February 20, 1996, as the second single from his sixth album, Mr. Smith. Based on a sample of Grace Jones' "My Jamaican Guy", it contains a guest appearance from LeShaun (who previously released a song with the same sample and theme in 1988 titled "Wild Thang"), while production was handled by Rashad "Ringo" Smith and LL Cool J. Its B-side was the album's previous single, "Hey Lover".

"Doin It" peaked at number nine on the Billboard Hot 100, and number seven on the Hot R&B/Hip-Hop Songs Billboard chart. In several interviews, both the artist and producer have stated that the instrumental was originally meant for the Notorious B.I.G. on his Life After Death album. The crowd noise heard throughout the song, shouting "Go Brooklyn!", is sampled from "Go Stetsa" by Stetsasonic. Furthermore, the hook of "Doin It" interpolates "Wild Thang" by 2 Much, a group LeShaun was part of.
