Ready to party like it's 1999? Janet Jackson and Missy Elliott's new song is here.

Friday, the duo released new song "BURNITUP!," the newest song off Jackson's upcoming Unbreakable album, and boy, does it sound like a real flashback. Elliott pronounces her entry with a loud "woooooo!" and a proclamation that she's about to "shut this down" before Jackson emerges to "dance like no one's watching" over a jaunty beat and air sirens. A little new jack is going on. It's nice.

"BURNITUP!" is the third song to be debuted off Unbreakable, following in the wake of the title track and the J. Cole–assisted lead single "No Sleeep." Prior to the new cut's release, it was performed as the opening number on Jackson's current world tour. So fret not, because you'll get plenty of chances to hear it live.

Unbreakable is due out Oct. 9. It's her first new album since 2008's DisciplineWe can't wait.
