Janet Jackson's first album in seven years is due out in just over a week and the singer has just shared one of the most anticipated songs from the 17-song tracklist, a collaboration with Missy Elliott. The release of "Burnitup!" comes after Jackson shared the album's title track, "Unbreakable," and the J. Cole-featuring "No Sleeep" earlier this summer. "Burnitup!" is produced by Dem Jointz and should be a dance floor essential in the very near future.
