Crazy in Love

Crazy in Love wasn't built from scratch — producer Rich Harrison sped up a 1970 Chi-Lites horn riff, and Beyonce almost turned it down before it became the biggest song of 2003. Jay-Z wrote his guest verse down the hall in one pass. The sample paperwork reportedly came together only after the record was already climbing the charts. Did the horns ever make you think of anything older than the song itself? Save this for later.
