1. "Crazy in Love" — Jay Z and Beyonce
It's been 10 years since "Crazy in Love" first hit the airwaves, cementing Jay and Bey as one of the hottest celebrity couples out there — even though they didn't even like to admit they were dating at the time. A lot has changed since then, clearly.
The song was named "The Best Pop Song Of The Century" by NME magazine in 2013.
