Since its 2009 debut in South Korea, CN Blue has been a bastion of rock in a music scene dominated by danceable electro-pop.

The band's lasting success has comforted some about the continuing mainstream appeal of rock, while detractors accuse it of peddling innocuous poppy sounds, even calling the group a "fake band."

In a recent interview with the four members, front man Jung Yong Hwa, 22, bassist Lee Jung Shin ,20, guitarist Lee Jong Hyun, 21, and drummer Kang Min Hyuk, 20, seemed to weigh in little on the controversy.
