Beyoncé released “Crazy in Love” in 2003.
The song was the lead single from her debut solo studio album, Dangerously in Love, released in June 2003. It features rapper Jay-Z and prominently samples the horn line from “Are You My Woman (Tell Me So)” by the Chi-Lites, giving the track its instantly recognizable opening.
“Crazy in Love” became Beyoncé’s first number-one single as a solo artist in the United States. It also topped charts in the United Kingdom and several other countries. The song’s music video, directed by Jake Nava, helped establish a visual style that became important throughout her career.
The single is sometimes confused with Beyoncé’s earlier group releases because Destiny’s Child was still part of her career history. Its 2003 release specifically marked her emergence as a solo headliner and introduced the sound of Dangerously in Love.
