Super Junior has announced that they'll be making a music program comeback through September 23rd's episode of 'Music Bank'! As reported earlier, they'll be releasing their follow-up song, "A-Cha",�from their repackaged album of the same name on the 19th. To accomodate those fans who don't want to own multiple copies of their "Mr. Simple" album, Super Junior will release the digital versions of their 4 new songs through music sites like Melon, Dosirak, Bugs, and Naver on that day. "A-Cha" is a song about holding onto a lover who seems to be unsure about what she wants. It's described to be a powerful dance track combining rock and electro house styles with an easy melody and sophisticated rhythm. 3 other tracks included in the new album are "Oops!!", "Andante", and "A Day". Members Leeteuk, Heechul, Shindong, Donghae, and Eunhyuk wrote the rap for "Oops!!", while Leeteuk and Super Junior-M member Henry composed "Andante". "A Day" is an emotional pop ballad that promises unchanging love. Stay tuned to allkpop for coverage on their first comeback stage! Source + Photo: TVreport via Nate
