After giving all of these several spins over the past several days, here's what I think.
2 dogs - first of all, regarding the woman in the song -- to quote the Beasties, "She's Crafty". Interesting story, and you have constructed a very catchy chorus: yesterday morning I woke up and found it stuck in my head. The piano part is not bad although I definitely get the vibe you are not primarily a pianist (it reminds me of an Eddiebangs song that is similarly based around a repetitive piano riff, don't recall which one off the top of my head but maybe "Brown Boxes"?) Furthermore, while the singing is also not bad, I suspect you are secretly a better singer when nobody is listening? The vocals feel a little bit restrained to me.
Beerland Security - Sounds like this was a fun song to play/record.

First several dozen times I heard this there were no vocals, so I just thought it was a cool little punkish ditty with an unusual guitar solo thrown in (not that the solo itself is unusual... nevermind). If these vocals had been there earlier, the drum part might have turned out somewhat different because now I can't get rid of the mental image of the Mystery Science Theater 3000 theme song. Sounds really good though, and I'm proud to have participated.
Dutova - in my opinion, the best song of a pretty good bunch of songs. The hook, the chorus, the guitar line -- this whole song has been in my head almost nonstop all week. I see you recently posted your lyrics, but the meaning is still a little bit left to the imagination, which is good because I want to imagine that behind all this pretty singing there's a dark little story behind it. Please don't ruin it for me by telling me I'm wrong. Definite highlight of the song is the instrumental breakdown bit right near 3:00 where it goes into those minor and/or diminished chords in the background. Nice.
Ethrikios - I think I like the introduction better than the rest of the song, though the whole thing is done well enough. Has a real good Cheap Trick/ random-other-Post-Beatles-band feeling; sounds great.
Ford's Theater Disaster - Pretty good song overall, no complaints, but I must say I am absolutely loving the backwards-masked Syd Barrett guitar leads (I believe "Dominoes" is the song I'm reminded of) -- great stuff.
Hijack + The Requests - Can't say much about this, because since I was hardly able to pick out any of the talking over the bassline, I probably missed the point of this song entirely.
Master Hyde - Very smooth, very hooky, excellent mixing and production work. The repetition of the title during the chorus reminds me of the 'Homer Simpson would say...' bit in The Def Author's "Mumbo Jumbo". Only smoother. Very smooooooth.
Paco del Stinko - Well produced and performed; instrumentally I can really dig this. However, the lyrics really turn me off. Lyrics are approximately dead last in my list of elements of songs I pay attention to, so for me to take note of them they have to be exceptionally good or exceptionally bad. Something about the words here really rubs me the wrong way, and I can't say for sure why that is.
Parliament of Owls - sounds pretty sweet, mostly, and the combination of instruments is fairly inventive. The layering of vocal parts is especially nice and adds a lot to the song, but may add too much-- literally. Just under a minute in, the vocals start to overload and this goes on most of the rest of the way, sporadically. Kind of makes it hard to listen to.
Pathetic Wannabees - The rushed rhythm that accompanies the vocal delivery during the verses is really cool. The contrast created between those bits and the straight-up bluesy style in between really makes the song. Good stuff.
Scomber - Can't say I understand how being framed is "better than being blamed", or even that there is a distinction between the two. The female vocals throughout are a nice touch, especially near the end where they are paired with that guitar lead section.
Sign Boy - A fairly well-done, and enjoyable, but not altogether very remarkable, example of industrial-pop. It was going fine until that sudden fade at the end, which was pretty weak.
Steve Durand - Pretty inventive instrumentation here, verging on "cute" but I think saying that would diminish the quality of the song. Seems like you enjoy playing with panning -- this is all over the place, stereo-wise. (Not a complaint). Some clever bits of words here, especially "give your junk some elegance". I like your clarinet part, I think those are criminally underused in modern music (with perhaps the exception of "When I'm Sixty-four").
Weakest Suit - Some of the chord structure here reminds me of that song "Brainville" by the Flaming Lips. Lyrically this sounds a bit more They Might Be Giants. A well-written song, although it sounds kind of hollow and empty. A lot can be done with just a guitar and vocals, but I'm not sure this arrangement is enough to carry the song on its own. It probably doesn't help that the whole thing sounds so distant...
Zinkline - There's this one specific place in the song, the little mishmash of voices after you say "anyone's guess", where I'm reminded of some song by the Cure (I think it might be "Catch" I am thinking of, but I can't be sure). All the rest of this sounds really good too; I've got half my brain arguing that this sounds exactly like something I've heard before but I can't put my finger on it, but possibly it's just such a well-crafted poppy song that it just feels instantly familiar. For now I will give you the benefit of the doubt and say, well done.
