What Micheal Jackson song is in the back round of Rhianna's song please don't stop the music ?

"The song samples Michael Jackson's 1983 single "Wanna Be Startin' Somethin'", which also sampled the Manu Dibango 1972 single "Soul Makossa", hence the "Mama say mama sa ma-makossa" that is interpolated in the bridge of the song. Jackson's trademark yells can be heard during the chorus and bridge."
