SS501's Kim Hyun Joong has finally unveiled his album jacket photo for his second mini-album comeback, "Lucky"! Dressed in a vintage casual look, Kim Hyun Joong made a 'dandy' transformation that all comes together for a stylish and charming concept.  His mini-album kicks off with a rock 'n' roll track titled "Do You Like That", which features a danceable beat and a powerful arrangement of band instruments.  There are a total of five tracks, including his title track, "Lucky", a traditional ballad titled "I'm Your Man", and a sweet love song titled "U". His title track itself features a rhythmical electric guitar and brass rock band sounds.  It's categorized as an up-tempo American punk rock song, something that Kim Hyun Joong has always wanted to try musically.  To make it possible, he's enlisted the help of the members of Day Break and Common Ground. Stay tuned for its release later this month! Source + Photos: Sports World via Naver
