Wonder Girls  is a South Korean girl group, whose current line-up is Yubin, Yeeun, Sunye, Sohee and Hyelim. They are managed by their producer, the singer-songwriter Park Jin-Young under his talent agency, JYP Entertainment. They are co-managed in the United States by Creative Artists Agency. The group's name, 'Wonder Girls', comes from the idea that they are "the girls who can amaze the world".

In late 2009, their song charted at number seventy-six on the Billboard Hot 100 chart, making the Wonder Girls the first South Korean group to enter the chart.
In 2010, Wonder Girls entered the Chinese market with the compilation album Wonder Girls that included Chinese language versions of "Tell Me", "Nobody" and "So Hot".

In 2012, Wonder Girls signed with DefStar Records, a subsidiary of Sony Music Japan, for their Japanese debut.

It was announced on November 26, 2012, that the group would be taking a break because of Sunye's marriage, with the other members focusing on their own activities.

T♔ARA

T-ara  is a South Korean girl group that debuted in 2009 under Core Contents Media. Before their debut, there was a high level of interest in the group; they were called the "Super Rookies" and had been training for three years prior.

Originally a five-member group composed of Jiae, Jiwon, Eunjung, Hyomin, and Jiyeon, they released their first song "Joheun Saram" (좋은 사람, "Good Person") for the soundtrack of the Korean drama Cinderella Man in April 2009. After Jiae and Jiwon withdrew from the group in June, T-ara debuted as a six-member group with the addition of Boram, Soyeon, and Qri in July 2009.

Their debut studio album Absolute First Album was released in December 2009 and spawned several hit singles including "Geojitmal", "TTL (Time to Love)", "TTL Listen 2", "Bo Peep Bo Peep", "Cheoeum Cheoreom" and "Neo Ttaemune Michyeo". The album was followed by the group's first extended play, Temptastic (2010), which included the top-five singles "Wae Ireoni" and "Yayaya". John Travolta Wannabe (2011) produced "Roly-Poly", the Gaon chart's number one single of the year, which earned the group several awards and nominations as well. In less than six months, the group released their third extended play Black Eyes (2011), which spawned three number one singles: "Cry Cry", "Uri Saranghaetjanha" and "Lovey-Dovey". The lead single, "Cry Cry", became the group's first number one on the Billboard Korea K-Pop Hot 100.

In 2011, T-ara signed a $4.3 million contract with the company J-ROCK for their Japanese debut, the highest out of all the girl groups debuting in Japan. Their major record label is EMI Music Japan while their management and promotional marketing takes place under J-ROCK. The group's first single was a remake of their 2009 hit "Bo Peep Bo Peep". It ranked at number one on the Oricon weekly charts with 49,712 copies sold, the first time a debuting Korean girl group has done so in the charts' history. T-ara released their debut Japanese studio album Jewelry Box in 2012, which peaked at number two on the Oricon charts.

The group has added three members to their lineup since debut: Hwayoung in 2010, Areum in June 2012, and Dani was announced to be joining the group in December 2012 (although she has yet to join the group). Hwayoung later departed the group in July 2012. T-ara uses a rotating leader system in which a different member of the group is elected as leader each year, in order to give both the group and the individual members the opportunity to grow in a new direction.
