I am your wikipedia
Just in case you ever hear Please Don't Stop the Music by Rihanna and wonder "What is she saying at that one bridgey part?" [ffwd to 2:30] let me save you some googling time since it's not in the lyrics online. Some sites refer it to it as "Ma ma se, Ma ma sa, ma ma coo sa" or "mama say mama say". It's actually something sampled from a Michael Jackson song which is sampled from "Soul Makossa. Tell it, wikipedia:
"Soul Makossa" is a 1972 single by Cameroonian makossa saxophonist Manu Dibango. [...] It is probably best remembered for the chanted vocal refrain "Mama-ko, mama-sa, ma-ka-ma-ko-ssa", which was also used in Michael Jackson's 1983 "Wanna Be Startin' Somethin'" (albeit in a different key with a not-so-monophonic melody) during the song's final bridge. It is also sampled in the hip hop song "Face Off" by artist Jay-Z on his album In My Lifetime, Vol. 1 as well as the single "Don't Stop the Music" by Rihanna. "Makossa" means "(I) dance" in Duala, a Cameroonian language."
