Which song by Beyoncé features rapper Jay-Z and begins with a famous horn sample?

Beyoncé’s song featuring Jay-Z and a famous horn sample is “Crazy in Love.”

Released in 2003, “Crazy in Love” was the lead single from Beyoncé’s debut solo album, Dangerously in Love. The recording combines contemporary R&B, hip-hop, funk, and soul influences, with production by Rich Harrison and Beyoncé.

Its prominent brass part derives from “Are You My Woman (Tell Me So),” a 1970 song by the Chi-Lites. Jay-Z contributes a rap verse, making the track both a solo breakthrough for Beyoncé and an early major musical collaboration between the two artists.

The single reached number one on the Billboard Hot 100 and won two Grammy Awards at the 2004 ceremony. The music video, directed by Jake Nava, is also remembered for its dance sequences and the choreography associated with the song’s opening.
