Which Beyoncé song features Jay-Z and opens with a famous brass riff?

Beyoncé’s song featuring Jay-Z and opening with a famous brass riff is “Crazy in Love.”

Released in 2003 as the lead single from Dangerously in Love, the track was built around a prominent sample from the Chi-Lites song “Are You My Woman (Tell Me So).” Rich Harrison produced the recording, while Jay-Z contributed a rap verse. The song’s energetic arrangement helped define Beyoncé’s early solo sound.

“Crazy in Love” became Beyoncé’s first solo number-one single on the Billboard Hot 100. Its music video, directed by Jake Nava, featured highly recognizable choreography and styling. The song is sometimes mixed up with “Drunk in Love,” another Beyoncé and Jay-Z collaboration, but “Crazy in Love” is the earlier 2003 hit with the signature horn-driven opening.
