This is sick.

You must... You Must... YOU MUST finish this one.
EDIT: After listening it a few more times, I must say the following: it feels like you have hijacked someone's piece and simply threw in the vocal samples with the drop into it. This sounds most obvious to me in the intro, as it is completely out of place, volume manipulation between your insert and the main song is clear-cut, and the clicking sound when the song starts playing again is another sign that the volume has been automated (the kick sample has been cut and only the release remained intact.)
Correct me if I'm wrong, but even though I may sound like a smart ass - this is what I and every other musician will figure out sooner or later.
BTW, please remember to use appropriate tags in the topic title.
