I like knowing there is some good speedcore on NG. As you can probably already imagine, it's very hard to constructively critisize speedcore, but I will try. I think you should add slighty more variation, it gets a little too repetitive in the middle. Also, I think the sample of the chick's voice should have some sort of an effect on it, maybe a reverb, or a flanger. That is all.
By the way, in the time it took me to write this review, this track gave me a massive migraine. That is a compliment. :)
its so crazy and the women voice is awsome
