Girl's Day recently made their comeback with 'Oh! My God', shedding their youthful and often comical colors with a more mature concept. While the girls' comeback was met with an explosive interest from fans and the like, many have expressed concern for the tough competition the girls will have to face against the overlapping comebacks between two other established acts,�4Minute and SISTAR.

"4Minute and SISTAR have all unveiled a powerful and sexy concept," said Girl's�Day, "And while our concept is somewhat similar, we have tried our best to balance out our usual image that many fans know us for, with a brand new, upgraded Girl's Day."

"Despite the overlapping promotion schedules with seniors girl groups, we will try our best to stay at the top of our game," continued Girls' Day, "We're confident in our music and hope to bring joy to our fans will with our new concept and performances."

Meanwhile, the girls have successfully wrapped up their showcase for their latest mini-album which features their title track "Oh! My God", an up-beat pop number that takes inspiration from a variety of electronic genres from dubstep to electropop.
