Jay-Z co-headlined Beyoncé’s 2004 hit “Crazy in Love.”
The song was released in 2003 as the lead single from Beyoncé’s debut solo album, Dangerously in Love. Jay-Z contributes a rap verse and appears in the song’s credited feature, making it a prominent collaboration between two major artists.
“Crazy in Love” became Beyoncé’s first solo number-one single on the Billboard Hot 100. The track also won Best R&B Song and Best Rap/Sung Collaboration at the 2004 Grammy Awards. Its horn-driven production was created by Rich Harrison and Beyoncé, with a sample from the Chi-Lites.
Jay-Z and Beyoncé later married in 2008 and collaborated on additional recordings, including “Drunk in Love” and the joint album Everything Is Love. The question refers specifically to the featured artist on “Crazy in Love,” not to the song’s producers or later collaborators.
