Jay-Z co-wrote and features on Beyoncé’s 2003 hit “Crazy in Love.”
The song appeared as the lead single from Beyoncé’s debut solo album, Dangerously in Love. It was written by Beyoncé, Jay-Z, Rich Harrison, and Eugene Record, with production by Harrison and Beyoncé. Its prominent horn sample comes from “Are You My Woman (Tell Me So),” recorded by the Chicago group the Chi-Lites.
Jay-Z contributes a rap verse, while Beyoncé delivers the main vocal performance. The song became an important early statement of their musical partnership, which continued across later recordings and albums.
“Crazy in Love” reached number one on the Billboard Hot 100 and won two Grammy Awards in 2004. Beyoncé and Jay-Z later married in 2008. The song is sometimes confused with “’03 Bonnie & Clyde,” an earlier collaboration between the two artists, but “Crazy in Love” was Beyoncé’s solo-era breakout single.
