David Michael Rodigan MBE (born 24 June 1951 on a military base in Hanover, Germany) is a British radio DJ who also performs as a selector for his sound system. Known for his selections of reggae and dancehall music, he has played on stations including Radio London, Capital 95.8, Kiss 100 and BFBS Radio 1.

He has stated that his passion for Jamaican music was initiated by watching Millie Small perform her 1964 hit My Boy Lollipop at the Ready Steady Go! TV show as a school boy. By the age of 15, David Rodigan was DJing at school dances and youth clubs. Leaving school in 1970, he spent a year studying economics before leaving to study drama. Despite pursuing an acting career, Rodigan kept his passion for music alive, selling records in Oxford then Putney, before obtaining a job on Radio London in 1978 to alternate with Tony Williams on the Reggae Rockers programme. A year later he was offered a permanent slot at Capital Radio to present Roots Rockers, which ran for 11 years. In 1990 a change in management and music policy at the station lead to David leaving to start a new show for Kiss FM when it relaunched that September as London's first legal 24-hour dance music station. He currently hosts the Sunday night slot from 11pm till 1am.

Robert Nesta "Bob" Marley, OM (6 February 1945 – 11 May 1981) was a Jamaican singer-songwriter and musician. He was the rhythm guitarist and lead singer for the ska, rocksteady and reggae band Bob Marley & The Wailers (1963–1981). Marley remains the most widely known and revered performer of reggae music, and is credited with helping spread both Jamaican music and the Rastafari movement to a worldwide audience.

Marley's music was heavily influenced by the social issues of his homeland, and he is considered to have given voice to the specific political and cultural nexus of Jamaica. His best-known hits include "I Shot the Sheriff", "No Woman, No Cry", "Could You Be Loved", "Stir It Up", "Get Up Stand Up", "Jamming", "Redemption Song", "One Love" and, "Three Little Birds", as well as the posthumous releases "Buffalo Soldier" and "Iron Lion Zion". The compilation album Legend (1984), released three years after his death, is reggae's best-selling album, going ten times Platinum which is also known as one Diamond in the U.S., and selling 25 million copies worldwide.

Naughty Boys (浮気なぼくら, Uwaki na bokura; "Naughty boys"^?) is the sixth album by Yellow Magic Orchestra, recorded from October 1982 to March 1983, and released on May 24, 1983. It contains the pop-oriented single "Kimi ni Mune Kyun", as well as a "preview" of "You've Got to Help Yourself", which was released in its full version on the companion album Naughty Boys Instrumental, and again with vocals on Service.

Naughty Boys was their final album to top the Oricon charts. After that, no technopop artist was able to reach No.1 until Perfume's 2008 album Game. "Kimi ni Mune Kyun" also became the highest charting single by a technopop artist on the Oricon charts, debuting at No. 2; a record the song retained until Perfume's "Love the World" debuted at No. 1 in 2008. "Ongaku" ("Music") was reportedly written by Ryuichi Sakamoto for his then-three-year-old daughter, Miu. Naughty Boys was re-released in 2004 in a double disc package alongside Naughty Boys Instrumental.

Various cover versions of "Kimi ni Mune Kyun" have been produced by later artists, including The Human League ("YMO Versus The Human League" in 1993),Asako Toki (in 2006), and Yuko Ando in 2009. Also in 2009, a cover of "Kimi ni Mune Kyun" was used as the ending theme song for the anime series Maria Holic, sung by Asami Sanada, Marina Inoue, and Yū Kobayashi, the voice actresses of the main characters.
