Which song gave Beyoncé her first solo number-one single in the United Kingdom?

“Crazy in Love” gave Beyoncé her first solo number-one single in the United Kingdom.

The song was released in 2003 as the lead single from Dangerously in Love. It topped the UK Singles Chart and also became Beyoncé’s first solo number-one on the US Billboard Hot 100.

Jay-Z appears on the track, which uses a prominent horn sample connected to the Chi-Lites song “Are You My Woman (Tell Me So).” The recording’s urgent vocal, rap feature, and brass-driven hook made it a defining early solo hit.

Beyoncé had already achieved major chart success with Destiny’s Child before this release. The distinction here is her solo career: “Crazy in Love” was not her first number-one song with the group, but her first UK solo chart-topper.
