"FuckWithMeYouKnowIGotIt" is a song by rapper Jay-Z recorded for his 12th studio album Magna Carta Holy Grail.
[1] David Ortiz of the Boston Red Sox used the song as his batter intro while stepping onto the field.
Jay-Z was supposed to add a guest verse to it, but when he heard the instrumental, he wanted the track for his album.
[2] Most of Jay-Z's verse was reused from "Living So Italian", an unreleased song from his and Kanye West's collaborative album Watch the Throne.
Rick Ross, however, recorded a solo version, dubbed "You Know I Got It (Reprise)," for his album Mastermind as a deluxe edition bonus track in 2014.
