35. Beyoncé feat Jay-Z, "Crazy in Love" (2003)
The night before Beyoncé turned in her 2003 debut Dangerously in Love, she asked Jay-Z for a favor. He heard the hit potential in "Crazy in Love" immediately; how those Chi-Lites horns and producer Rich Harrison's go-go percussion could catapult the Destiny's Child singer to solo stardom. "He played the song and went crazy," Young Guru, Jay's personal engineer, said to MTV News. "Crazy in Love" would be the breakout moment for Bey, topping the Billboard Hot 100 for eight weeks – though a big asset ended up being the chemistry between the then-rumored couple. She oozes sex appeal, while he raps about chinchilla furs in a futile effort to keep his cool.
