Review...
Ok, that Voice sounds so corny. You could've at least vocoded it with a synth, or a saw to make it sound cool.
That first song wasn't really hardcore. Felt more like some kind of light trance... Not really hardcore... In fact, the second song is not really hardcore either. They need more kick and distortion on the kick.
The third song is sounding good. Nice distorted gabber kick... but the melodies do not work. They sound really dischord and not good at all. The best possible would be the second and the third combined.
You picked a really bad voice, I can't even understand it.
This first breakcore song isn't hardcore at all. The amen needs more punch. I shoulda given breakcore a go... I can do so much to an amen, it's amazing... Hardcore glitching at 3:35. Did you use dblue-glitch? If so, it sounds like that... Or you could've just glitched it yourself. The break needs more punch, but the glitch was nice.
Second breakcore... Sounds not hardcore and doesn't get hardcore in 20 seconds... Yeah, it isn't hardcore or breakcore... Just a bunch of breaks... Not breakcore at all...
Speedcore... first song sounds cool... Actually nice glitch, the noise is nice, but the voice sucks. Really. It's a bit too chaotic... The speed needs more definition, it should not just be a roll. At 6:30, that's what I'm talking about with speedcore, he puts the tempo to good use, like artists like that should. I don't know who it is, because I can't understand the voice. You should've narrated it yourself...
Last song isn't speedcore or breakcore... Its not hardcore enough to be either.
Overall, a lot of these songs weren't really hardcore at all. The two tracks that stood out to me were the third hardcore song and the second speedcore song. The rest barely fit the genres they were supposed to be.
I don't mean to be harsh, but this wasn't really all too good. It was lacking a lot of things, and many submissions were not very good. I really should have done something.
Overall 6/10, but 5/5 for nice try.
