Nice.
I find the bass fine, personally. I do find the vocals too loud though, in the first tune. I understand that rap lyrics have to be heard, but I just find that it really over-powered the "beats". Also, I have no idea if it would sound better, but I'd try less reverb on the vocals. There's not alot, but I can hear it, and I'm used to rap lyrics being a little drier.
Everything esle is fine. I just think people wouldn't move to this tune as much as they should since the vocals push the music a little too far back.
This song needs more bass.
Just kidding. Sounds cool. What's the UFO sound taking off? I've gotta have that.
