The dancehall pop style of music began to gain attention in the early 2000s. This new fusion style of dancehall and pop was characterized by the adoption of pop song formatting, including choruses and melodies, and a larger fusion of English and Patois in lyrics. Its early contributing artists include Sean Paul, Rihanna, Beyonce, and Kevin Lyttle. It was Sean Paul's sophomore album, Dutty Rock (2002), that started the trend of the dancehall and pop fusion. Sean Paul's second single off the album, "Get Busy" (2003), became the first dancehall-pop inspired song to reach #1 on the US Billboard Hot 100. The song received high acclaim and mainstream success, selling over 2 million copies in the United States, and went on to win Best Reggae Album at the 46th Annual Grammy Awards in 2003. Fellow Caribbean singer Rihanna also incorporated dancehall pop music into her debut album, "Music of the Sun" (2005), with her debut single "Pon De Replay" (2005), was compared to Beyonce and Sean Paul's hit #1 US Billboard Hot 100 single "Baby Boy" (2003) because of their combined "dancehall-pop mixture". While majority of the song's lyrics are in English, the title which is written in Rihanna's native Bajan patois, as well as the vocal tone of the song being dubbed to have a "reggae vocal cadence". This is a nod to the Caribbean roots of dancehall pop existing both within musical style and language. Other Caribbean artists such as Kevin Lyttle, Notch, Rupee, as well as American artists such as Lumidee and Nina Sky, released songs that incorporated dancehall pop rhythms in the 2000s decade.
