I should really start using MTVMG2 more. I am noticing a lot of great songs have been produced with it.
I am loving this track and the samples you have used. I am not sure what the "razor" kind of sample is called. I guess it is some kind of sawtooth sample, but anyways, it is really cool and works great in your song. Reminds me of a 8-bit videogame sound.
I personally think this would be cooler if you had a harder hitting kick though, but I guess that's just a personal preference. Other than that this is kick ass!
