A-side and B-side originally referred to the two sides of gramophone records on which singles were released beginning in the 1950s. The terms have come to refer to the types of song conventionally placed on each side of the record, with the A-side being the featured song (the one that the record producer hopes will receive radio airplay and become a "hit"), while the B-side, or flipside, is a secondary song that often does not appear on the artist's LP.

The earliest 10-inch, 78 rpm, shellac records were single sided. Double sided recordings, with one song on each side, were introduced in Europe by Columbia Records and by the late 1910s they had become the norm in both Europe and the USA. There were no record charts until the 1930s, and radio stations (by and large) did not play recorded music until the 1950s (when top 40 radio overtook full-service network radio). In this time, A-sides and B-sides existed, but neither side was considered more important; the "side" did not convey anything about the content of the record.

Michael David Rapaport (born March 20, 1970) is an American, actor, director and comedian. He has acted in more than forty films since the early 1990s. For his television credits he's best known for his roles on the television series Boston Public, Prison Break, Friends, and The War at Home.

Rapaport was born to a Jewish family in Manhattan, New York City, the son of June Brody, a New York radio personality, and David Rapaport, a radio program manager. As a teenager he idolized actors, and fellow New Yorkers, Robert De Niro and Christopher Walken. He was expelled from high school and moved to Los Angeles, California to try stand-up comedy.

Rapaport has appeared in both dramatic and comedic roles on film and television. His movie roles include starring alongside Eddie Murphy in Metro, as a wisecracking marine biologist in Deep Blue Sea, and as a naive college student whose loneliness drives him to become a racist skinhead in Higher Learning. Many credit his breakout role with the independent film Zebrahead. His other best known film role was in True Romance as Dick Ritchie. Rapaport costarred in the Fox sitcom The War at Home, in which he played an "average Joe" type dealing with the everyday challenges of family life. The sitcom debuted in September 2005, and was cancelled in May 2007.

Laouni Mouhid, commonly known by his alias La Fouine (English: The Weasel) or Fouiskin (born December 25, 1981 in Trappes, Yvelines), is a French rapper of Moroccan origins from the city of Trappes, Yvelines in the Paris western suburbs. He is an established figure in French rap. La Fouine signed with Sony Records in 2003 and released his debut album, Bourré au son, in 2005. La Fouine released his second album, Aller-Retour, on March 12, 2007. The American beatmaker Focus produced four songs on the album. His most recent album, Mes Repères, was released on February 23, 2009 and is two times gold record in France. His new album, a double CD intitled "La Fouine Vs Laouni," released on February 14 for Valentine's Day, was inspired by the two sides of himself, through his career and experience of his daily life. The first one, La Fouine, a character he created to "entertain people, La Fouine is very cunning, materialistic, bad boy and so vulgar ... it's not really me" said the artist. The second one Laouni (his real name) talks about things he lived in his youth, so his rap is sincere and moving. The week of album's release, more than 25 621 copies were sold in France, a feat for a hip hop artist. He has also his own label "Banlieue Sale Music" and his own clothing line called "Street Swagg".
