"Crazy in Love" is a song from Beyoncé's 2003 debut solo album Dangerously in Love. Beyoncé wrote the song with Rich Harrison, Jay Z, and Eugene Record, and produced it with Harrison. "Crazy in Love" is an R&B and pop love song that incorporates elements of hip hop, soul, and 1970s-style funk music. Its lyrics describe a romantic obsession that causes the protagonist to act out of character. Jay Z contributes a rapped verse to the song and is credited as a featured performer. The French horn-based hook samples "Are You My Woman (Tell Me So)," a 1970 song by the Chi-Lites.
