Happy 5th Anniversary, Sistar! Watch the K-Pop Girl Group's 5 Best Music Videos


SISTAR members attend a press conference prior to attending the K-Pop stage, "M Countdown" at the KCON 2015 Japan in the Saitama Super Arena in Saitama on April 22, 2015.

In Sistar's signature greeting to fans, the girl group shout "We're the B.E.S.T. Sistar!" When it comes to the charts, the fourpiece has put in work to make that statement as true as possible these last five years; crafting hit single after hit single and becoming famous in South Korea as a nearly unbeatable force when it comes to digital sales.

Hyolyn, Soyu, Dasom and Bora -- aka Sistar -- first debuted on the K-pop scene on June 3, 2010 with the release of their electronic/hip-hop track "Push Push" that came accompanied with a fun, but rather cheap, gas station-themed music video. Since then, the girls have become one of the most dependable acts for eye-catching and, at times, boundary-pushing visuals with a new single and video confirmed to drop before the end of the month.

To celebrate the act's five-year anniversary, Billboard counts down their best visuals to date.
