"Shake Ya Ass", also known by its clean title, "Shake It Fast", is the first single released from American rapper Mystikal's album, Let's Get Ready. It also features uncredited vocals from Pharrell. It was released July 18, 2000 and produced by The Neptunes. It was a huge success for Mystikal, peaking at #13 on the Billboard Hot 100, #3 on the Hot R&B/Hip-Hop Songs and #7 on the Hot Rap Singles. Both the song and music video (directed by Little X) received heavy radio airplay and it has possibly become Mystikal's most well-known song. "Shake Ya Ass" was followed by another top 20 hit, "Danger (Been So Long)".
