Having made their return on Mnet M! Countdown last week, boy band ZE:A flocked the stage once more for a commendable performance of their comeback song. Proving that quality is indeed greater than quantity, the nine members of ZE:A performed All Day with strong vocals and synchronized dancing that was unlike a rookie show. It's amazing what kind of effect a song choice can make on one's musical career. In terms of the concept, All Day wasn't a significant change from Mazeltov. However, the former song is a zeallion zillion times more addicting than the latter one. In addition, the title was appropriately chosen, as it accurately describes for how long the track will remain stuck in your head. Indeed, I have been replaying ZE:A's new song all day and even all night. http://www.youtube.com/watch?v=BOtRHmcD-w4 The rookie idol group still has a long way to go before they reach the top, but they are definitely on the right path in getting there.
