After School 'Because of You' was not released by Pledis but leaked

On the 23rd,SNSD Taeyeon's Chin Chin Radio program was accindetally aired After School's new track. Once approved, the radio stations are then supposed to wait until the album is released, prior to playing it on the air.Its not Taeyeon fault,is MBC FM4U fault.

Pledis Entertainment stated:

"It is true that the songs can be aired once it is approved, however, songs are usually aired after the official release date of the album. Considering the varying amounts of time each broadcasting company takes to review, we normally send the songs in early. Wouldn't the pattern be broken if the broadcasting companies aired them beforehand?"
