This is not exactly a new release but I saw Joon perform this song at this weeks Music Bank and I loved the song. The MV is really cool too, especially because of the eye candy, as it features our eternal Sunbae (AKA SS501's Hyun Joong) looking especially beautiful. I really love it when he goes 'ttona, ttona' ^^
But in the end, this video is about Joon (AKA Prince Song) and he rocked this. (less info)
