repetative, but it works. Try adding to it
Simple, but you got the part.
You made what your title said. And that's it. A decent hardcore song. Good beat, but it needs to have more to it.
You definently got the hardcore part down.
Your using pretty basic sounding instruments in this, it's all around the beat. The song flowed well, but it felt like it doesn't have much variety. The noises are really harsh, which is good, you've met the goal of this song in my opinion, I liked it, I'd say continue on making more hardcore, maybe try trance and techno songs for inspiration in this genre?
