Which Beyoncé song featuring Jay-Z won the 2004 Grammy for Best R&B Song?

“Crazy in Love” won the 2004 Grammy Award for Best R&B Song.

The song was released in 2003 as the lead single from Beyoncé's debut solo album, Dangerously in Love. It features rapper Jay-Z and was built around a prominent sample from the Chi-Lites' 1970 song “Are You My Woman (Tell Me So).” Its brassy arrangement and repeated vocal hook became central to the track's sound.

The song helped establish Beyoncé's solo identity and reached number one in several countries. It is sometimes confused with “Drunk in Love,” another Beyoncé and Jay-Z collaboration that appeared much later on the album Beyoncé.

At the 46th Annual Grammy Awards in 2004, “Crazy in Love” won Best R&B Song and Best Rap/Sung Collaboration. Its music video also became closely associated with Beyoncé's early solo era.
