Shake Ya Ass

"Shake Ya Ass", also known by its clean title "Shake It Fast", is a song by American rapper Mystikal, released on July 18, 2000 as the first single from his fourth album, Let's Get Ready. Produced by the Neptunes, the song features a hook performed by Pharrell Williams, who is uncredited on various releases of the song. It was Mystikal's biggest commercial success, peaking at number 13 on the Billboard Hot 100, number three on the Hot R&B/Hip-Hop Songs chart and number seven on the Hot Rap Singles chart. Both the song and music video (directed by Little X) received heavy radio airplay and it has become Mystikal's most popular song, along with its similarly successful follow-up, "Danger (Been So Long)"—which the Neptunes also produced.
