2. Beyonce, "Single Ladies"
"Single Ladies" was more than a monster single between 2008 and 2009, it was also the song and visual that made Beyoncé as big as she is today and solidified her diva status. The black-and-white clip features just the singer and two back-up dancers in black leotards doing fun, catchy choreography (inspired by Gwen Verdon's 1960s moves to "Mexican Breakfast") to the hit tune. The video created its own dance craze and inspired fans to learn and imitate the dance across social media.
