“Crazy in Love” was Beyoncé’s debut solo single to reach number one on the US Billboard Hot 100.
Released in 2003, the song led Beyoncé’s first solo album, Dangerously in Love. Its production combines a forceful horn riff, a dance-oriented rhythm, and a guest rap by Jay-Z. The song’s style helped distinguish Beyoncé’s solo work from the group-based sound audiences associated with Destiny’s Child.
“Crazy in Love” spent eight weeks at number one on the Billboard Hot 100. It also topped charts in countries including the United Kingdom and Ireland, making it an international breakthrough rather than only a US success.
Later Beyoncé singles such as “Irreplaceable,” “Single Ladies (Put a Ring on It),” and “Break My Soul” also reached number one. That later success can make it easy to overlook that “Crazy in Love” established the initial solo chart milestone.
