Which song became Beyoncé’s first solo Billboard Hot 100 number-one hit in 2003?

“Crazy in Love” became Beyoncé’s first solo Billboard Hot 100 number-one hit in 2003.

The song was released as the lead single from Dangerously in Love and reached the top of the U.S. Billboard Hot 100 soon after its release. It marked a major transition from Beyoncé’s established success with Destiny’s Child to her independent career as a solo performer.

The recording features Jay-Z and was produced by Rich Harrison and Beyoncé, with additional writing credits including Jay-Z. Its brass hook comes from a sample of “Are You My Woman (Tell Me So)” by the Chi-Lites.

Beyoncé’s next solo number-one single was “Baby Boy,” featuring Sean Paul. That distinction matters because “Crazy in Love” is not merely an early hit: it was the first of her solo songs to reach the top of the Billboard Hot 100.
