A sophisticated style switch-up and contributors in Charli XCX and MNEK leads to positive results.

With their Fancy You album, TWICE put a refreshing twist on their image and it's led to K-pop group's biggest response for an album yet.

The leading K-pop girl group's Fancy You EP debuts at No. 4 on Billboard's World Albums chart. The six-song set that has songwriting contributions from several members as well as top pop names like Charli XCX, MNEK and Black Eyed Pileseung sold more than 1,000 copies in the week ending April 25, according to Nielsen Music, after its April 22 release. Overall, this marks TWICE's best one-week sales for an album stateside.

Fancy You marks TWICE's ninth album to hit the Top 10 on World Albums and tenth overall entry. TWICE hit No. 1 in late 2017 with their Twicetagram full-length LP. In fact, the only TWICE record not to enter the Top 10 was their debut EP The Story Begins. Still, at the time they were just the second-ever K-pop girl group to send both their debut single and album to the Billboard charts.

Today, The Story Begins is actually TWICE's best-selling album in America with 4,000 copies sold. Interestingly though, the group's first Japanese album #Twice is their most-consumed album in America -- which accounts for streaming and sales -- with 69,000 equivalent album units. This is likely due to the fact it was available on all streaming platforms, like Spotify where the group's full Korean discography was only added in the past year, as one of the few ways for fans to listen to their hit songs, even if in Japanese.

Over on the World Digital Song Sales chart, new single "Fancy" debuts at No. 4 after selling 2,000 copies in the week ending April 25. It's in the Top 10 for best first-week sales for TWICE songs with past singles like "Likey" and "Knock Knock" both surpassing it with 3,000 copies in their debut weeks. To date, "TT" is the band's best-selling song in America with a whopping 33,000 copies sold to date.

While TWICE has risen to the top of the K-pop scene with their continously cheerful image, Fancy You marks an exciting change-up as the girl group pushes towards their fourth year together. Even on their most ambitious tracks, TWICE has stayed true to a playful and bright image but on "Fancy," the ninesome pushed towards a stronger and sophisticated look with edgier fashion and more aggressive choreography. But if the group looked a bit different, TWICE's cheery, feel-good sound remained intact with longtime collaborator Black Eyed Pilseung (responsible for some of their biggest hits like "TT," "Cheer Up" and "Likey") bringing an irresistible electro-pop treat of a single. Fancy You also sees the girls continuing their trend for interesting and genre-bending album tracks with standouts in the breezy vibe of the minimalistically lush "Strawberry," plus the euphoric, empowering "Girls Like Us" that has production credits from Charli XCX and MNEK and wouldn't sound out of a place on a Top 40 playlist.

With an upcoming world tour that includes their first-ever U.S. concert dates held in three arenas across the country, TWICE's image refresh seems to be the exact right step to help the group expand past Asia -- where they've been in command for years.
