2012 release, the sixth full length from the hit-making Korean boyband. The album marked the return of band member Kangin, who left the group for mandatory army service in 2009. Band leader Leeteuk expressed that they had wanted to try out different music and dance styles in this album, as the songs from their third to fifth albums have been similar. Member Sungmin further explained saying, "The songs on our previous albums mostly featured mechanical sounds effects and catchy rhythms, but this time we tried to diversify into various genres such as ballads, R&B, and covers of old songs, without relying on special audio effects as much". The soulful house and addictive chorus of the title track helped this album win Album of the Year at the Mnet Asian Music Awards.
