Nihilanth - Awesome, it's like a mix between alternative and metal. It's great, vocals would just make it that much better.
Static Bones - This is a cool song. I could totally see this in Guitar Hero. Vocals aren't nessesary, but would be nice.
The Majestic IV: Resonance Cascade - Beautiful. I love the feel of it. Vocals would be a nice touch to complete it.
Questionable Ethics - Good song, love the electric guitar. It's a tad repetitive and first, adding vocals would help that. And then: BOOM! Awesome job with the drums!
Statue of a Statue - Really nice meloncholy song. It brings up a lot of images, and that's what makes a song good. Vocals would be nice, to put some story behind it all.
Aerospike Engine - Really cool! I like this one a lot, it's up beat and epic. Vocals would be nice because it has so much build up. Also, what's with the Star Trek? :)
Nakazakicho Station - Nice, I can't put a genre on it, and I think that's why I like it. My only complaint is the guitar sounds a bit off tune, but I'm sure it's supposed to.
Exoskeleton (Live) - Awesome. The only thing I could recommend are vocals.
Good luck with your band!
