I'm really picky when it comes to dubstep songs. But it ruins the original song that I really like. the instrumentals are really clean, but I am not into the glitch kind of dubstep. 7/10 Whoops. I really like the jumpy beat to it, but the singer's voice is mehhhh. The electronic keyboard is sweet though. 7.5/10
I don't know a lot about vocals, but personally I prefer the vocals from the original version. Though, it's good to see they made some varation on the song instead of just doing exactly the same. 6/10
