# Rollin' (Brave Girls song)

"Rollin'" (Korean: 롤린) is a song by South Korean girl group Brave Girls. It was released on March 7, 2017, as the lead single from the EP of the same name. Written by Brave Brothers, Two Champ, and Chakun, the song has been characterized as a dance-pop track that incorporates elements of tropical house. A rearranged version of the song titled "Rollin' (New Version)" was released on August 11, 2018, as a thank-you to the group's fans for their support of the original version.
A sleeper hit, "Rollin" initially failed to chart in South Korea following its release. Four years later, the song experienced a sudden surge in popularity when a compilation video of Brave Girls performing it for the South Korean military went viral in the country in February 2021. It soon became a nationwide hit, and achieved number one on both the Gaon Digital Chart and the K-pop Hot 100, where it remained for five and six non-consecutive weeks respectively.

## Release and promotion

"Rollin'" was originally released on March 7, 2017, as the title track and lead single from Brave Girls' fourth mini album Rollin'. The group began promotional activities for the song later that day with their first domestic television music show performance on SBS MTV's The Show, followed by appearances on MBC Music's Show Champion on March 8, Mnet's M Countdown on March 9, SBS's Inkigayo on March 12, and KBS2's Music Bank on March 24. On August 11, 2018, the group released "Rollin' (New Version)", a rearranged version of the song, as a gift to fans for their passionate support of the song over the course of the previous year and a half.
In March 2021, in response to the song's surge in popularity after going viral, Brave Girls resumed promotions for the song.

## Music video

On March 3, 2017, the first teaser for the music video for "Rollin'" was released through Brave Entertainment's website and on Brave Girls' official YouTube channel. The teaser shows the girls in a dark room sitting in chairs with a storm as a background. It was rated 19+ in South Korea. On March 3, the second and final teaser was released, showing the group dance for the song and scenes with members sitting on a sofa.
The music video was released on March 7, 2017, in conjunction with the EP. The video shows the girls dancing in a room with a dark background, showing the Moon and thunder. Chairs were incorporated into key parts of the song's choreography. The video was restricted on YouTube for viewers under eighteen. The following day, a choreography-only version was released; it was not age-restricted. On March 9, Brave Entertainment released a clean version of the original music video, in which scenes of the girls lying on each other had been removed.

## Reception

Prior to the song's release, KBS deemed "Rollin'" unfit for broadcast, stating that certain parts of the lyrics contained a slang word which was too vulgar. Brave Entertainment responded that they would revise the lyrics and resubmit the song for reevaluation. On March 8, 2017, news media reported that the modified version had been reviewed and accepted by KBS.
In late February 2021, four years after the song was released, a compilation video of Brave Girls performing the song became viral on YouTube. The song subsequently received a surge in popularity and rose to the top of real-time music charts. It soon achieved a "perfect all-kill", simultaneously topping all real-time charts in South Korea, and became the first song by a group to do so in 2021. On March 22, 2021, "Rollin'" topped the charts for 198 hours, making Brave Girls the girl group with the most "perfect all-kills", a record formerly held by girl group Twice who had a total of 197 PAKs.
On June 12, 2024, Carmen Chin included "Rollin'" in NME's list of the 15 best K-pop summer songs of all time, praising the track's "straightforward, upbeat vibe".
