"Head over Heels" is the debut single by American girl group Allure, released in February 1997. It is from their 1997 eponymous debut album. The song features a rap by American rapper Nas, and also contains a sample of "The Bridge" by MC Shan. It peaked at No. 35 on the Billboard Hot 100.
Critical reception
Ralph Tee from Music Week's RM commented, "Mariah Carey launches her new label through Epic with this bump'n'grindin' street soul churner by these four New York soul divas. To help things along, Nas makes a guest appearance with a few words, while Mariah herself appears briefly in the video. As a song it's a little predictable, but its melody grows on you after a few spins and, considering everybody involved, you can only expect this to do well."
