This is my first post here, so I decided to make it a good one. I tried to be positive and critical which is a tight rope to walk.
Mission From Proton - catchy and hit all the beats I wanted it to. Predictable isn't always bad, the piano came in exactly when I wanted it to like magic, and there's an art to that. I dug the guitar recording and separation, but wished the drums were a tad louder.
Steve Durand - Vocals are the most opinionated instrument, there are plenty of bands I love vocals where my friends hate it and vice versa. I can honestly say I just couldn't get into the the singing style. If perhaps it were a little goofy or cartoony, I would have liked it more?
heine - onomonopia much? Classic to the core, I can honestly say this just isn't my style or genre preference, but that doesn't stop it from being a job well done. You nailed it.
caravan ray - I like the intro a lot! Once the guitars come in, I feel it sounds a bit more like the other entries, but it has a unique flavor I like in the drum beat, though I can't peg whether it's sonic quality, performance, or combination. I really dig the end too. A lot. Well done.
Berkeley Social Scene - I dug the sonic quality a lot, except the kick drum which I felt needed more old school punch. The vocals sat in the mix well without being too loud. Guitar solo for the win.
Billy And The Psychotics - Yes. Another guitar solo that makes me happy. I dig the whole thing.
Trotsky + Marx - The timing issues give it a flavor I like some of the time, but sometimes it's so off it's distracting. It also gets a little repetitive for me. I find the panning interesting and old school, well done there for nailing that vibe.
The Yyarrell Brothers Band - the open high hat sound during the chorus makes me weep. Otherwise, I dig it. Good vocals and guitar.
Toshiro - I'm happy at this point just to be hearing something substantially different from the other entries. The high's are a little harsh, but otherwise this whole track works for me.
Eggnog Adam - Interesting drum and I like the very 90s chord changes. I'd like to hear more punch in the kick drum in the later part in the track. Cool track. And I love the references to one of my favorite movies of all time. You also nailed the vocals.
Manhattan Glutton - I like the guitar panning (what can I say, I'm a sucker for good stereo separation). Good track overall, with great guitars and vocals standing out. I felt it went on a little long, but that might be because the other tracks were all so short.
Juliet's Happy Dagger - The production was fine, but I can honestly say this isn't my stylistic genre preference at all, so it's hard for me to really comment.
chthXchthXchthX - I like heavy, but this may actually be a little much even for me, especially with the drum compression sound (which some would like, so it's not bad). I also feel that being substantially instrumental, it was hard to tell how much it related to the theme. But, at the very least, it was interesting.
MC Who Izzy and Kapitano - another stand out for being different, which I appreciate. But the vocals are really hard to understand and sound like they have a low bitrate warble. I'd probably dig it more if I could understand it.
Bubble Pipe Media + Viktor Walters - I'm Biased

I'm happy with how it turned out considering we only had two sessions to work on it. I'm a big fan of dark moody pieces that don't quite fit into any genre, so I got what I wanted out of it. The writer and I wanted a plot of a server in the office that was a cyborg who was feeling ignored. I'm not sure if that really came through, but he was the literal heart/center of the office. I also wanted to make sure I did something that no one else was likely to do something similar, and I think I succeeded.
@SchlimminyCricket and Manhattan Glutton: I considered and even tried a more melodic chorus briefly, but decided it just didn't fit with the music I already had from session 1. (session 1 was music, session 2 was vocals, lyrics, and mixing)
@EggNogAdam: I'm glad you dug the recording, I pride myself on my sonic sensibilities, so I'm glad they worked for you. Having a ridiculously full and distorted guitar-like instrument is not far fetched for me, maybe the next time I do a darkish track.
@Who_Izzy "Is this dubstep?": I don't know. Is it?

Funny enough, I really like music with dubstep elements, but seldom do I like anything that is flow blown dubstep. 'Coming up just short' is better than falling flat, so thanks!
@Missions to Proton: Glad you dug it! I would have liked a little more variation as well, my lyricist and I have considered revisiting it if we come of with a coherent enough plan/idea.
