Idol groups 2NE1, Beast, and T-ara prepare to dominate music charts once again with their June-July comebacks.

KPOP representatives have already shown interest as to what change in music and which new concept will be born; the reason being 2NE1, Beast, and T-ara's known dominance on music charts.

Planning their comeback in the middle of June, 2NE1 is a group who promotes several title tracks rather than being limited to one. These tracks not only have the ability to place high on charts, but also to maintain long runs on the charts.

Coming back at the end of June, Beast is a group who possesses great presence on music charts among male idol groups. Last year's 'On a Rainy Day' managed to stay on charts for a long run, as Beast is able to succeed with both dance tracks and ballads.

Group T-ara is preparing their comeback for July 7. T-ara wiped charts with 2011's 'Roly Poly' and this year's 'Lovey Dovey.' Their new song 'Day by Day' is already receiving hype for its choreography by Beyonce's 'Single Ladies' choreographer Jonte Moaning.
