Category F5 is the seventh studio album by American rapper Twista. The album marks the first collaboration with Chicago producer the Legendary Traxster since 2004's Kamikaze. The album was released on July 14, 2009. Originally scheduled to feature Kanye West, Akon, Busta Rhymes, Mr. Criminal, Tech N9ne, and Static Major, guest appearances were pared down as many of the recorded songs were leaked, including the song "Problems" featuring Tech N9ne, which was cut because of sample-clearance problems. The track "She Got It" (produced by Jim Jonsin & featuring Bobby Valentino) was cut because the tracks were not 100% ready. "All Right" (produced by Kanye West) was included on iTunes as a bonus track.
