Argh!
Don't listen to the guy below me. Who cares if it's not in the genre YOU think it should be in? There is no HARDSTYLE genre to submit to on newgrounds, so you have to submit it to the next closest thing. The melody is definitely in the trance-ish key anyways. Also, lol@metalcore.
Anyways, it's pretty nice. The kick lacks depth, and it drowns out the synth. In many hardstyle songs, the kick also provides bass, but here it doesn't. So some bass would do this good. Just fix the minor equalizing problems, and maybe add something.
