What was Beyoncé’s first solo No. 1 single on the US Billboard Hot 100?

Beyoncé’s first solo No. 1 single on the US Billboard Hot 100 was “Crazy in Love.”

Released in 2003, the song became the lead single from her debut solo album, Dangerously in Love. It features rapper Jay-Z and prominently samples the horn riff from “Are You My Woman (Tell Me So)” by the Chi-Lites, giving the track its instantly recognizable opening.

“Crazy in Love” reached number one in the United States and several other countries. Its energetic production and distinctive video helped establish Beyoncé as a major solo artist after her success with Destiny’s Child.

The song is often mixed up with “Baby Boy,” which also became a major hit from the same album, and “Single Ladies,” which came years later. “Crazy in Love” was the first of those songs to lead her solo chart career.
