Magic is part k-pop, part Oneway. On one hand the hook is catchy and attention-grabbing, but on the other hand it's got the sense of epic-ness during the choruses, and an actual melody to boast. The song as has traces of Ne-yo beats and Usher melodies, but the way they were pieced together and the over all sound is kpop all the way. Nevermind that it's in Korean, it sounds like it was produced by a Korean. That's what I want from kpop acts - identity.
I got from these guys, and this song, the perfect combination of mainstream/generic and a clear direction. Need I ask more?
