Rapping (also known as emceeing,MCing,spitting (bars), or rhyming) refers to "spoken or chanted rhyming lyrics". The art form can be broken down into different components, as in the book How to Rap where it is separated into “content”, “flow” (rhythm and rhyme), and “delivery”. Rapping is distinct from spoken word poetry in that it is performed in time to a beat.

Rapping is a primary ingredient in hip hop music and reggae, but the phenomenon predates hip hop culture by centuries. It can also be found in alternative rock such as that of Cake and the Red Hot Chili Peppers. Rapping is also used in Kwaito music, a genre that originated in Johannesburg, South Africa and is composed of hip hop elements. Rapping can be delivered over a beat or without accompaniment. Stylistically, rap occupies a gray area among speech, prose, poetry, and song. The use of the word to describe quick speech or repartee long predates the musical form, meaning originally "to hit". The word had been used in British English since the 16th century, and specifically meaning "to say" since the 18th. It was part of the African American dialect of English in the 1960s meaning "to converse", and very soon after that in its present usage as a term denoting the musical style. Today, the terms "rap" and "rapping" are so closely associated with hip hop music that many use the terms interchangeably.

Howard Allan Stern (born January 12, 1954) is an American radio personality, television host, author, actor and photographer best known for his radio show which was nationally syndicated from 1986 to 2005. He gained wide recognition in the 1990s where he was labeled a "shock jock" for his outspoken and sometimes controversial style. Stern has been exclusive to Sirius XM Radio, a subscription-based satellite radio service, since 2006. The son of a former recording and radio engineer, Stern wished to pursue a career in radio at the age of five. While at Boston University he worked at the campus station WTBU before a brief stint at WNTN in Newton, Massachusetts.

He developed his on-air personality when he landed positions at WRNW in Briarcliff Manor, WCCC in Hartford and WWWW in Detroit. In 1981, he was paired with his current newscaster and co-host Robin Quivers at WWDC in Washington, D.C. Stern then moved to WNBC in New York City in 1982 to host afternoons until his firing in 1985. He re-emerged on WXRK that year, and became one of the most popular radio personalities during his 20-year tenure at the station. Stern's show is the most-fined radio program, after the Federal Communications Commission (FCC) issued fines to station licensees for allegedly indecent material that totaled $2.5 million. Stern has won Billboard's Nationally Syndicated Air Personality of the Year award eight times, and is one of the highest-paid figures in radio.
