Haven't voted or really made up my mind on how I'm going to vote this time around, but here are my initial thoughts.
Astrolamb
The vocals sound strong and clear to me, didn't notice any pitch problems, which plague just about everything I sing. The character of your voice fits the song nicely. The guitar and piano sound great together after you first sing the title, but it feels like you just tagged the title at the end of a section, especially at the end where it seems most out of place. Good song, but a failure to meet the spirit of the challenge.
Berkeley Social Scene
Another really strong track from BSS. Great guitar sounds, singing, prostyle. Lyrically it's a song about shopping addiction, I think. If you change 'Watching the Riot' to 'I can't Deny it' it doesn't really change the song. In my estimation, It uses the words of the title, but little if any of the meaning or context. I don't buy watching riots as a metaphor for compulsive shopping on QVC. Having said that it's an enjoyable and listenable song, with a righteous guitar solo.
The Chocolate Chips
The build up at the beginning is really good. I'm pretty pumped by 0:14 but I feel like the melody loses some steam by 0:20, but I can't say exactly why. Watching the Riots .. maybe this is what the end of society looks like. Also a listenable song, with the words, the context, and clocking in at 01:36 it didn't overstay its welcome.

Literally abut watching riots, good imagery, nice 80s sound, well written, efficient. Nicely done. The chorus to me is a bit of a downer, not sure why my ears expect/want it to be somehow more upbeat.
Jerkatorium
Was not ever intended to be a full song, but it turned into one for fun. I feel this could legitimately be a song about riotous anarchy by an unimaginative punk band.
Klownhole
Nice pipes, some pretty kick ass on-topic punk singing. I wish I could sing like that without my neighbors calling the cops, must feel awesome. It's a bit long though, and I feel like you spent maybe too much time exploring the no/yes dichotomy. I assume sounding like an asshole is part of the act, bravo.
Margret Benson and the Cheese Trio
Attempted song collage, with a hat tip to the the collage art I had hoped would be selected for the cover art. There really isn't enough variation to make it that interesting sadly, but it was fun to write and record the bits.
Nick Soma
Nice fast punk song about watching riots that sounds vaguely like Suicidal Tendencies to me. The 'are you aware / wake up' bit gets me amped up like good punk songs are supposed to do. Dig it. Some of the vocals sound muddy and lost in the mix though, especially in the be beginning where they set the tone for the song.
PFMKM
I like the line about your streets becoming a firing range. Pretty multi-tracked singing 'fire' in watch the fire, the hooter also sounds appropriate. I also like the line about burning the tyrant's crown. Even though I was initially turned off by somewhat schmaltzy melody, it grew on me.
Skadaddle
Cool song. I guess the line about the telephone camera being your gun could be about watching riots, but it's a song about a relationship. Not sure I care, it's a good engaging song, and I really like the raspy voice of the singer. Enjoyed it every time I've listened, but again I don't feel it meets the challenge of writing a song with an arbitrary title/topic.
Sunday Guts
Another great sounding tune by Sunday Guts. Really dig the vocals, especially what sound like staccato sampled backup vocals, really adds something nice to the sound. The laughing / talking bit doesn't really work that well for me. The language of sinners and proverbs bugs me, but I still dig the song because it takes me to my pop happy place, which Sunday Guts seems to have a knack for finding.
