After achieving major success over the past two years with cheerful, hook-filled hits, Korean girl group TWICE returned on Sunday (Feb. 19) with their latest single “Knock Knock.”

The new song is a sugary, pop confection from the act's their newly released EP, Twicecoaster: Lane 2, the reissue of last year’s Twicecoaster: Lane 1. Lane 2 features two new songs -- “Knock Knock” and the ballad “Ice Cream”-- in addition to Lane 1’s original seven. The update also features several remixes and instrumental versions of TWICE’s previous singles “TT,” “Cheer Up” and “Like Ooh-Ahh.”

“Knock Knock” favors a twinkling bubblegum pop style and an ‘80s-inspired house beat, with an earworm of a chorus that cheerfully pounds its way through the song. The bright tune weaves electronic and rock elements into its infectious melody, most noticeably during the post-chorus bridge that is entirely devoid of vocals, giving “Knock Knock” a hint of the complexity that’s propelled TWICE’s previous singles to the top of Korean music charts.   

The music video for “Knock Knock” features TWICE playing around at a slumber party, anxiously waiting to see who is knocking on their door. Unexpectedly, the group's producer Park Jinyoung, the founder of JYP Entertainment, arrives only to be greeted with disappointed expressions from the nine members. The next “Knock Knock” brings the delivery of a book featuring TWICE in their Halloween and fairytale-themed “TT” outfits, which the women read until they realize it’s snowing outside and run into the white powder in pajamas and earmuffs.

The video ends with the group getting locked out and knocking on the door, before shifting to the final scene of “TT,” which showed two young trick-or-treaters staring at a door with mysterious knocking -- an apparent a hint to the now-released follow up “Knock Knock.”

Since debuting with “Like Ooh-Ahh” in 2015 (after being formed through a reality television show), TWICE has become one of Korea’s most popular young acts, continuously impressing with their charming singles and music videos. All three of TWICE's previous EPs appeared on the World Albums chart, with Twicecoaster: Lane 1 peaking the highest at No. 3. Additionally, “TT” was one of Korea’s most popular songs of 2016.
