"Crazy in Love" is a song recorded by American singer Beyoncé, featuring a rap verse and ad-libs from her future husband Jay-Z from her debut solo studio album Dangerously in Love (2003). The song was released as her official debut single and as the album's lead single on May 14, 2003, through Columbia Records and Music World Entertainment. Both artists wrote and composed the song in collaboration with Rich Harrison and Eugene Record; the former also produced it with Beyoncé. Using samples from the Chi-Lites's 1970 song "Are You My Woman (Tell Me So)", "Crazy in Love" is a pop, hip hop and R&B love song that incorporates elements of soul, and 1970s-style funk music. Its lyrics describe a romantic obsession that causes the protagonist to act out of character.
