"Get Ready" was the only single released from Mase's second album, Double Up. It was released on May 25, 1999, produced by Sean "Puffy" Combs, Teddy Riley and Andreao "Fanatic" Heard" and featured R&B group, Blackstreet, it contains a sample of "A Night to Remember", performed by Shalamar.

"Get Ready" was Mase's poorest performing single, due in large part to the fact that the rapper retired from music before the song's official release and did not promote or perform the song publicly. It failed to match the success as his previous three singles, only making it to 25 on the Bubbling Under Hot 100 Singles (125 on the U.S. Charts) and #50 on the Hot R&B/Hip-Hop Singles & Tracks.
