"A cause" (meaning "Because") is the third and last single released in France from Céline Dion's French album D'elles. It was sent to the radio stations on January 21, 2008. At the same time "Alone" was released to promote Dion's English album Taking Chances. Both tracks were included on the "A cause" promotional single.

"A cause" was written by Françoise Dorin ("Et s'il n'en restait qu'une (je serais celle-là)") and Jacques Veneruso ("Sous le vent," "Tout l'or des hommes" and "Je ne vous oublie pas" among others), who also produced this track.

Céline Dion performed it during the French TF1 TV special dedicated to the issue of her album D'elles, in May 2007. She also performed "A cause" on Vivement Dimanche during her visit in France, in November 2007. The performance was supposed to be broadcast on France 2 in May 2008, during the French leg of the Taking Chances Tour, but it was cancelled.

"A cause" was remixed by Dj Rien - French producer, composer and remixer.

There was no music video made for this track.

Céline Marie Claudette Dion, CC OQ, (French pronunciation: [selin djɔ̃] ( listen); born March 30, 1968), is a Canadian singer. Born to a large family from Charlemagne, Quebec, Dion emerged as a teen star in the French-speaking world after her manager and future husband René Angélil mortgaged his home to finance her first record. In 1990, she released the English-language album Unison, establishing herself as a viable pop artist in North America and other English-speaking areas of the world.

Dion had first gained international recognition in the 1980s by winning both the 1982 Yamaha World Popular Song Festival and the 1988 Eurovision Song Contest. Following a series of French albums in the early 1980s, she signed on to CBS Records Canada in 1986. During the 1990s, with the help of Angélil, she achieved worldwide fame after signing with Epic Records and releasing several English albums along with additional French albums, becoming one of the most successful artists in pop music history. However, in 1999 at the height of her success, Dion announced a hiatus from entertainment in order to start a family and spend time with her husband, who had been diagnosed with cancer. She returned to the top of pop music in 2002 and signed a three-year (later extended to almost five years) contract to perform nightly in a five-star theatrical show at the Colosseum at Caesars Palace, Paradise, Nevada.

Robert James "Bob" Ritchie (born January 17, 1971), known by his stage name Kid Rock, is an American singer-songwriter, musician, multi-instrumentalist and rapper with five Grammy Awards nominations. Kid Rock released several studio albums that mostly went unnoticed before his 1998 record Devil Without a Cause, released with Atlantic Records, sold 11 million albums behind the hits, "Bawitdaba", "Cowboy", and "Only God Knows Why". In 2000, he released The History of Rock, a compilation of remixed and remastered versions of songs from previous albums as well as the hit single, "American Bad Ass" and the previously unreleased "Abortion".

Kid Rock released the follow-up in 2001, Cocky. After a slow start, his country-flavored hit "Picture" with Sheryl Crow resurrected the album and it went gold as a single and pushed the album's sales over 5 million. It was followed by 2003's self-titled release, which went platinum in the USA and reached No. 8 on the Billboard charts. In 2006 he released Live Trucker, a greatest hits live album that went mostly unnoticed.
