Samples...
The samples are what killed this song. I liked the lazor quote. A lot. I LOVED the wobbles in the intro and later in the song. But the drum samples absolutely KILLED this song. The kick was bad. It wasn't low enough, it didn't ring. The snare used in most of the song as well as the hat just made me wanna puke. Re-do this with more dubstep appropriate drum samples, and you'll have a pretty good track on your hands.
