The album is produced by music director Choi Cheol Ho, producer Kim Jong Cheon, and producer Seo Hyun Il, who also produced Jang’s Japanese debut single, Let Me Cry.
When the album was released in May in Japan, it topped the Oricon Daily and Weekly Charts.
Jang is the first male solo artist to release a full-length album in Japan since Moriyama Naota did in 2004. He’s also the first foreign artist to top the Oricon Chart in eight years. Having shown off his great voice and singing skills in such drama series as You’re Beautiful and Marry Me, Mary!, he’s again showing off his soft yet powerful voice in this album.
He also proves his talent as a composer and an artist by writing “In My Dream,” a song for SNSD’s Yoona, who worked with him in the drama series Love Rain.
The album contains lots of rock numbers that show off Jang’s crazy yet sexy charms. It topped the Online Sales Chart of Tower Records in Japan by selling 130,000 copies before it was released. The title of the album, Just Crazy, implies Jang’s passion for his work and life.
The album contains “200 Miles,” the first track of the album that attracted a lot of attention as an opening song of the popular Japanese animated film Fairy Tail; ”Crazy Crazy Crazy,” a rock number that starts with a dreamlike sound; “Let Me Cry,” which topped the Oricon Weekly Chart when it was released in April; “Bye Bye Bye (Album Version),” a song for a commercial for an alcoholic beverage; and “Rain.”
