Needs more power.

First of all, that's really a suckish acapella, even if it is the original. You can still hear some of the original synths together with the vocals. You should've either searched for another one or made it yourself (yes, that's possible).
Ok, what I wanted to say is: your song needs more body. The sawtooth you used is pretty nice, but the beat is so silly. It needs more BING BANG BOOM!, just like the original, know what I mean? Maybe if you sped it up a bit it would sound better already. I think it also has to do with the fact that the guitar synth Martin Solveig used is missing. Maybe you should've replaced it with another synth, like a pluck or something.

Also, this is my 100th audio review, so I'm giving you a 9 instead of an 8. Lucky guy :)
