A common move with popular K-Pop groups on hiatus is to split themselves into other projects. In particular, the sub-unit concept has proven popular with members able to experiment to bring something fresh for fans. Girls' Generation  created the sub-unit Girls' Generation - TTS (also known as Taetiseo) who this week became the highest charting K-Pop act on the Billboard 200 with their EP "Twinkle" -- at No. 126 on this week's Billboard 200  with 3,000 copies sold according to Nielsen SoundScan.
It was only March 17 this year that BIGBANG spent one week on the chart at No. 150.
The act also makes big moves on the Heatseekers Albums  chart, debuting at No. 2, only to be bested by Human Nature  who performed on "Dancing With The Stars" last week. The EP does top the World Albums chart  with less than two days of its worldwide release sales counted for Billboard charts.
The act was tipped to be a hot one with over 10 million collective views of the three teaser videos featuring a different member in each. To possibly encourage orders, if fans bought the entire EP package, they would receive special tracks of the members introducing the EP songs. Additionally, if fans e-mailed an address associated with SMTown, the group's label, with a picture to prove they bought the album, they were in the running to receive a special gift from Girls' Generation - TTS.
The sub-unit is made up of three members: one of the group's most powerful vocalists Taeyeon, the charismatic and English-speaking Tiffany, and the group's youngest member Seohyun. They are also known as Taetiseo; a combination of their three names.
While Girls' Generation is known for their sexy concepts and choreography (from the slick first English single "The Boys"  to playing dress up on "Mr. Taxi" ), the sub-unit sees a completely revamped girls with a focus on funky vocals and vibrant outfits.
In other K-Pop news, two boy bands make appearances on the World Albums chart with B.A.P. making their comeback this week with an EP titled "Power" as well as U-KISS debuting at No. 10 and No. 12 respectively.
