“Crazy in Love”
"Crazy in Love" begins much like the inauguration of Beyonce's solo career, with horns glaring and a combo of modern funk, soul, pop and -- thanks to her hubby -- hip-hop. "It's the horn hook," Beyoncé noted. "It has this go-go feel to it, this old-school feel. I wasn't sure if people were going to get it." People got it. Released in May 2003, the song would serve as the summer's anthem. And, Jayonce fans would mark the beginning of the diva's willingness to admit that she was head over heels for the hip-hop star.
