"...i gave it a 5/10 myself and i made it."
There's just your problem: There are thousands (if not millions) of Newgrounds members that frequent the Audio Portal, bringing about thousands if not millions of different minds. They don't always think that a 5/10 is what you deserve.
Quite personally, I agree fully with Mystery-Moon-Pie-Aud, that metal is more than just guitars and drums. Not only that, but the quality is poor and the synching leaves much to be desired.
all i have is guitar and drums though. i have sad equipment really. i have no professional way of recording, no mixing and editing software other then windows recording. i also use my amp to record to record into the computer, instead of directly. i dont use a metronome or even write the songs. i just make it up as i go. really i put no effort into any of my recording tracks. bare minimum dude.
The song is an average made song, there is nothing that brings me out and says "Whoa, let me hear that song again". Just general riffs and drums, there is more to metal than that.
never meant for it to be anything more then average really. a 3 though? a little harsh dontcha think. i mean, i gave it a 5/10 myself and i made it.
