Which Grammy-winning Beyoncé song was the first No. 1 single of her solo career?

“Crazy in Love” was the first No. 1 single of Beyoncé’s solo career.

The song was released in 2003 as the lead single from Dangerously in Love, Beyoncé’s first solo studio album. It reached number one on the Billboard Hot 100 and established her solo career after her years as a leading member of Destiny’s Child.

Jay-Z appears on the track, which also uses a prominent sample from the Chi-Lites’ 1970 song “Are You My Woman (Tell Me So).” Its energetic production, horn arrangement, and choreography helped make it an immediate signature song.

Later Beyoncé singles, including “Irreplaceable,” “Single Ladies (Put a Ring on It),” and “Break My Soul,” also topped major charts. That later success can make the chronology easy to mix up. “Crazy in Love” is the key first solo No. 1, and it remains one of the defining opening statements of her recording career.
