Seohyun performs during the press conference of her first solo album 'Don't Say No' on Jan. 16, 2017 in Seoul, South Korea.

As the third member of Girls' Generation to drop an official solo album, Seohyun follows in line with her senior bandmates for an impressive showing on multiple Billboard charts this week.

Most notably, Seohyun's debut EP Don't Say No debuts at No. 3 on the World Albums chart making it the biggest K-pop album in America this week. That's right in line with her fellow Girls' Generation members Tiffany (whose I Just Wanna Dance EP also debuted at No. 3) and just behind the group's leader Taeyeon, who scored a No. 1 when her debut EP I: The 1st Mini Album debuted at the top spot, while her sophomore EP Why started at No. 2.

Don't Say No also makes it into the Heatseekers Albums chart, a ranking which sees fewer K-pop albums, starting at No. 23. Comparatively, Tiffany has peaked at No. 10 on Heatseekers while Taeyeon peaked at No. 5 after her two releases.

Despite being its youngest member, Seohyun has consistently been a strong presence in Girls' Generation with the 25-year-old becoming even more of a prominent vocalist as the nearly 10-year-old girl group grows older. With Don't Say No, Seohyun makes an even stronger case to be one to watch by offering a slew of songs that all boast different moods and feels, but are wrapped in a bubblegum-pop sheen. While the EP's title track boasts an Ariana Grande–esque R&B-pop sound, Seohyun also moves to dark trap-pop on "Magic," charming acoustic pop on "Lonely Love," and even tries her hand at tropical house-pop with standout "Hello" featuring Eric Nam.

While this is the first appearance for Seohyun as a solo artist on World and Heatseekers Albums, Don't Say No marks her third appearance on World Albums after charting entries as a part of both Girls' Generation and Girls' Generation-TTS, the sub-splinter group made up of herself, Taeyeon and Tiffany.
