Which song gave Beyoncé her first U.S. Billboard Hot 100 number-one single?

“Crazy in Love” gave Beyoncé her first U.S. Billboard Hot 100 number-one single.

Released in 2003, “Crazy in Love” features rapper Jay-Z and was produced by Rich Harrison, Beyoncé, and Jay-Z. Its distinctive horn line draws from “Are You My Woman (Tell Me So)” by the Chi-Lites, giving the track one of its most recognizable musical signatures.

The song topped the Billboard Hot 100 and became the lead single from Beyoncé’s debut solo album, Dangerously in Love. It also reached number one in the United Kingdom and several other countries. The accompanying music video helped establish the energetic visual style associated with Beyoncé’s early solo era.

People sometimes identify “Single Ladies” or “Irreplaceable” as her first U.S. number one, but both came later. “Crazy in Love” was the breakthrough chart leader that began her solo Hot 100 run.
