The real secret to making a good heavy metal song is about five years of experience making heavy metal music. Once you cross that threshold I can assure you that writing heavy metal songs get's kinds of easier. Seriously though, I loved to hear your attempt to bring the sound out even if you aren't metal mozart. Experimentation is key to getting better at art or music. Wish I still had that kind of energy in me but most of my crap these days is the same old bull shit.

If your still going to make this kind of music you should listen to other artists in the metal category that are doing the same thing. Ask them how to properly mix some of your sounds. I might not be a metal person but I'd recommend sidechaining the bass with the drum kit to help de-mud some of the mix. Growing up, newgrounds let me collaborate with all kinds of people and I'd be shocked if that resource dried up. Don't be afraid to reach out to people! The next metal track you output could be a collaboration with someone who has the same program as you. I've done that with StanSB, Sessilenomad, Sinerider... I'm sure a few others too but I'm forgetful in my old age.

Keep up the good work Razor!
