16. Beyoncé feat. Jay-Z – "Drunk in Love"
It's so close to the most important duet of 2013 and 2014, if only Jay Z hadn't invoked Ike Turner and Mike Tyson in his rap. Ostensibly a glimpse into the spouses' boozy, loving nights, Bey's not singing her best – listen to the a cappella and experience true pitchiness – but she's at her most heartfelt, which is why this song has quickly become a women's bar-sing-along jam for bosses and bachelorette parties. "We woke up in the kitchen like, 'How did this shit happen?'" she wonders, and Jay's slurred, slovenly-minded raps offer an answer: drunk, in love, you know how it goes.
