The first one is...
simply beyond my own comprehension.
I really haven't heard anything quite like it. Hell, I haven't even heard of the genre. I like the flavor, despite the fact that I'm slow to accept new ideas

However, it gets somewhat repetitive; changing it up a little can do good things.
It feels like I'm fighting some incredible alien boss battle.

IMO that's a pretty good job.
And the second one is pretty retro-video-game-like (I'm not sure if this is the right term, but... chiptune-ish?). Prolly due to simple waveforms and sounds, but it really takes me back to the days when sonic, mario, and games like them were still around.
They just don't make classics like them anymore.
Short & simplistic :]
I'm always half-asleep, and I hate dubstep.
Also, you know that other, way more awesome Nomnom guy who shows up on EQD sometimes? THAT PERSON IS NOT ME.
We just happen to have similar pseudonyms.
