“Crazy in Love” became Beyoncé’s first solo single to reach No. 1 on the US Billboard Hot 100. Released in 2003, the song features rapper Jay-Z and served as the lead single from Dangerously in Love.
The track was written by Beyoncé, Jay-Z, Rich Harrison, and Eugene Record. Its distinctive horn-based hook samples “Are You My Woman (Tell Me So),” a 1970 song by the Chicago soul group the Chi-Lites. The energetic production combines pop, R&B, hip-hop, and funk elements.
The song’s music video, directed by Jake Nava, features Beyoncé performing a series of dance sequences, including the well-known opening routine. It became one of the defining visual and musical statements of her early solo career.
“Baby Boy,” also from Dangerously in Love, followed “Crazy in Love” as a major hit, but it was not the first solo Beyoncé single to top the Hot 100. The song won two Grammy Awards in 2004.
