Task: Question Answering
Input (English): Passage: "Don't Stop the Music" was written and produced by the Norwegian production duo StarGate, with additional songwriting by Tawanna Dabney. Michael Jackson received a songwriting credit for the sampling of the line "Mama-say, mama-sa, ma-ma-ko-ssa" from his 1983 single "Wanna Be Startin' Somethin'". Tim Sturges and Phillip Ramos provided additional production for the song. It was recorded at Battery Studios in New York City and Westlake Recording Studios in Los Angeles by Mikkel S. Eriksen and Al Hemberger. Phil Tan and Josh Houghkirk mixed the single, and StarGate provided vocal production and instrumentation.In February 2009, Cameroonian musician Manu Dibango filed a lawsuit claiming that "Don't Stop the Music" and "Wanna Be Startin' Somethin'" used the "Mama-say, mama-sa, ma-ma-ko-ssa" hook without his permission. According to Dibango, the line is from his 1972 single "Soul Makossa". Agence France-Presse reported that Jackson admitted that he borrowed the line for "Wanna Be Startin' Somethin'" and settled out of court. When Rihanna asked Jackson in 2007 for permission to sample the line, he allegedly approved the request without contacting Dibango beforehand. Dibango's attorneys brought the case before a court in Paris, demanding €500,000 in damages and asking for Sony BMG, EMI and Warner Music to be "barred from receiving 'mama-say mama-sa'-related income until the matter is resolved". The judge ruled that Dibango's claim was inadmissible: a year earlier, a different Paris-area judge had required Universal Music to include Dibango's name in the liner notes of future French releases of "Don't Stop the Music", and at the time of this earlier court appearance, Dibango had withdrawn legal action, thereby waiving his moral right to seek further damages."Don't Stop the Music" was the fourth single from Rihanna's third album, Good Girl Gone Bad (2007). Before its release, two promotional remixes of the song (Solitaire's More Drama and the Wideboys Club Mix) were added to digital outlets in Canada and the United States on August 7, 2007. On September 7, an EP of the single was released via the iTunes Store in some countries including Australia, Italy, New Zealand and Spain. The EP contains the Wideboys Club Mix and instrumental and album versions of the song. That day, "Don't Stop the Music" was released as a CD single in Germany with the same material as the EP and the song's music video. The following month, it was released as a CD single in France. Def Jam Recordings provided the song to contemporary hit radio stations in the United States on January 15, 2008, and to rhythmic contemporary stations a week later. Nine remixes, including the album version of the song, were released on May 14 to digital outlets in territories including Australia, Germany, New Zealand and Spain. 
Question: What is the first name of the person Rhianna got permission from to use the line "Mama-say, mama-sa, ma-ma-ko-ssa?"?
