Very nice video
Violent, yet not in the blood and gore style which is usual for Newgrounds, and it's a nice change.
This is the way Flash animated music videos should be. Simple yet fun. If you find the right song and try not to put too much into it so you can focus more on the basic animation, and it can look great. That's my problem. I go way over my head when trying to animate with music. This was a very nice cartoon to a song I am embarassed to know the words to.
