Music of the Sun is the debut studio album by Barbadian singer Rihanna. It was released on August 29, 2005, by Def Jam Recordings. Prior to signing with Def Jam, Rihanna was discovered by record producer Evan Rogers in Barbados, who helped Rihanna record demo tapes to send out to several record labels. Jay-Z, the former chief executive officer (CEO) and president of Def Jam, was given Rihanna's demo by Jay Brown, his A&R at Def Jam, and invited her to audition for the label after hearing what turned out to be her first single, "Pon de Replay". She auditioned for Jay-Z and L.A. Reid, the former CEO and president of record label group The Island Def Jam Music Group, and was signed on the spot to prevent her from signing with another record label. After Rihanna was signed by Jay-Z, she continued to work with Rogers and his production partner Carl Sturken, as well as other music producers such as Poke and Tone, D. "Supa Dups" Chin-quee, and Stargate. Music of the Sun features vocals from Canadian rapper Kardinal Offishall, music group J-Status, and Jamaican singer Vybz Kartel. Music of the Sun is a dance-pop,[1] dancehall,[2] and R&B[2] album; it also incorporates Caribbean music and reggae. Music of the Sun received generally mixed reviews from music critics, some of whom complimented its dancehall and Caribbean-inspired songs, while others criticized some of the production. Commercially, the album was a modest success, debuting at number ten on the US Billboard 200 and number six on the US Top R&B/Hip-Hop Albums. In addition, it peaked within the top 40 of album charts in Germany, New Zealand, Switzerland and the United Kingdom. It produced two singles – "Pon de Replay" and "If It's Lovin' that You Want" – the former of which peaked at number two on the US Billboard Hot 100 and number one on the US Dance Club Songs. Music of the Sun was certified Platinum by the Recording Industry Association of America (RIAA). Rihanna promoted the album along with her next release with her debut concert tour, Rihanna: Live in Concert.
