Which Beyoncé single became her first solo U.S. number-one hit in 2003?

“Crazy in Love” became Beyoncé’s first solo U.S. number-one hit in 2003.

The song was released as the lead single from Dangerously in Love, her debut solo studio album. It features a rap appearance by Jay-Z and was produced by Rich Harrison and Beyoncé. Its prominent horn sample comes from the Chi-Lites’ “Are You My Woman (Tell Me So).”

The single reached the top of the Billboard Hot 100 and remained there for eight weeks. It also topped charts in the United Kingdom and several other countries. The music video helped establish Beyoncé’s visual identity as a solo performer.

Beyoncé later achieved additional major singles, including “Irreplaceable,” “Single Ladies (Put a Ring on It),” and “Halo.” Those songs are associated with later albums and milestones, but “Crazy in Love” specifically marks her first solo U.S. chart-topper.
