Graded Song: 2PM "A.D.T.O.Y"

Not too familiar with 2PM or their music. All I know is that my favourite K-Rapper/singer Jay Park was in 2PM at one point and that Taecyeon, the main rapper was in a K-Drama with Suzy from Miss A and from Eunjung T-ARA. The first title track from their comeback album was Come Back When You Hear This Song, which did nothing for me. However, JYP did the smart thing and released two title track instead of one. This one is "A.D.T.O.Y" (All Day I Think of You).
I'm not sure if I mentioned this before but JYP usually has the weakest output of K-Pop songs for me personally. I can never really get into them like I can with YG, SM and some of the smaller companies. However, I was blown away by this. The song went straight to the point, pulling you in with the chorus and switches from very strong rapping to some of the most soulful singing I've heard in a K-Pop song in a while. All backed by dubstep flourishes and orchestra. Ummm, but whoever was doing that falsetto needs to stop. He sounded like Justin Bieber in "Boyfriend" and he does it for a minute straight.
Final Grade: A-
