What is "burnitup!"

"Burnitup!" (stylized as "BURNITUP!") is a song by American singer Janet Jackson featuring rapper Missy Elliott recorded for Jackson's eleventh studio album, Unbreakable (2015). It was written and produced by Jackson, Dem Jointz, Jimmy Jam and Terry Lewis and Elliott. The song marked the fourth time Jackson and Elliott collaborated together. The first was on 1998 remixes of " Go Deep," the second in 2001 on a remix of " Son of a Gun" from All for You (2001), and the last on "The 1" from Discipline (2008).

"Burnitup!" was released as a promotional single from the album on September 25, 2015, while a digital promo single containing the album's version and a radio edit was released on October 5, 2015. The dance song contains electronic beats, processed vocal samples, "crisp" house drums, glossy keys and thick synth-bass in its instrumentation. Lyrically, the song finds Jackson promising to "dance like no one's watching" and "show you how to burn it up", while Elliot hypes the crowd. The song received positive reviews from critics, who commended the song for being a "club-ready" track and very energetic. It is the opening track from Jackson's 2015–16 Unbreakable World Tour.
