Beyoncé's solo debut single 'Crazy in Love' is famous for its triumphant horn riff, which was sampled from the 1970 song 'Are You My Woman? (Tell Me So)' by The Chi-Lites. Producer Rich Harrison had the beat for years but couldn't find an artist who could handle its high energy until he met Beyoncé. She reportedly loved the riff but was initially unsure about the heavy instrumentation. The song also features a guest verse by Jay-Z, which he recorded in just ten minutes at 3:00 AM on the day the song was due to be finished. The track spent eight consecutive weeks at number one on the Billboard Hot 100 and won two Grammy Awards. It is widely regarded as one of the best pop songs of the 2000s, signaling Beyoncé’s successful transition from Destiny’s Child to a global solo powerhouse. The song’s 'uh-oh, uh-oh' hook remains one of the most recognizable vocal melodies in modern music.
