Which Beyoncé song became her first solo US number-one single?

“Crazy in Love” became Beyoncé’s first solo US number-one single. Released in 2003, the song features rapper Jay-Z and served as the lead single from her debut solo album, Dangerously in Love.

The track was written by Beyoncé, Jay-Z, Rich Harrison, and Eugene Record. Its distinctive brass hook was built around a sample of “Are You My Woman (Tell Me So),” originally performed by the Chi-Lites. The energetic production and choreography helped establish Beyoncé’s solo identity after her years with Destiny’s Child.

“Crazy in Love” reached number one on the Billboard Hot 100 and became an international hit. It also won two Grammy Awards in 2004, including Best R&B Song and Best Rap/Sung Collaboration. “Baby Boy,” another song from the same album, later became a US number-one single, but “Crazy in Love” was the first.
