2AM’s JoKwon makes his solo debut with “I’m Da One,” an upbeat dance-pop track packed tight with all the color and charm we’ve seen him display on variety shows. Leave it to King JoKwon to beat the famine that plagues his kingdom, take back the throne, and throw a total kickass pop-art party. And the result? The best of both worlds — the 2AM leader’s strong and steady vocals and alter ego Kkap Kwon’s over-the-top acting and dancing skills.
