"Almost Human" - This sounds like Diablos to me! He's barely on the Wiki; I'll have to fix that. But anyway, Diablos is an AU version of the DIA's Irvine who wound up in the PPC one day. He tried to insert himself into the lives of our Irvine and his acquaintances, but his origins* and rather villainous demeanor set everyone off their ease. He eventually became a danger to the group, all while acting like he was the victimized one. Hence:

What did I ever do to you
That you should treat me this way?
Is it really such a crime
For an angel to speak his mind?
. . .
What did I ever do so wrong
That you should cast me from grace
Though I love to rule in Hell here
How I miss the taste of Heaven

And of course, the repetition of "I'm just like you."

"Mr. Pinstripe Suit" - I'm guessing this is the obvious one you were alluding to. This is the Mysterious Somebody: Voodoo = the Force, and the way Mr. Pinstripe Suit strolling into town all swag-ly matches the MS's rise to power in HQ. Plus, the MS was keeping all kinds of secrets from the PPC—he's "got the answers we all wanna know."

"Red Like Roses Part II" - Ugh, first I need to go listen to Part I. *Is reminded he's multiple seasons behind in Red Vs. Blue*

Anyway. Since these seem to be canon characters singing to each other, it's a little tricky assigning the lyrics a PPC meaning. It's mostly calling to mind the relationship between the Reader and the Aviator, from what I've read about it. Haven't been keeping up with modern PPC stuff while I work on the archive, so my info may be off.

"Halfman's Song" - I would say this was a bit of an anthem for Mary Sues, but I think it's just a little too self-aware of the narrator's faults. (There are some who are born distinguished/There are some who are raised in praise/But me I was always the last in line) It's definitely got the themes of envy for canon and manipulative tactics down, though.

Beware, beware of the words I twist
I am small but my reach is long
. . .
The land is a blooming orchard
With fruits so juicy and ripe
With a clink of a coin loose the lion’s loin
. . .
Molding puppets from their minds of clay

I’m no man of honor
Myself is my true king

"La Bo—seriously? You're just being mean, now. This is literally a song about dancing. Oh, wait, no. This is "Bomba," not "Bamba." Huh.

Haven't kept up on my Spanish, but this first stanza is mostly familiar. A drink that changes your life, something drives you madly delighted . . . "smile water?" Blah blah blah, it's Bleepka, obviously.

BLEEEEEEPKAAAAAA

—doctorlit tiene una poca de gracia por él y por ti.

*Considering our Irvine is a copy of the Final Fantasy VIII canon, and Diablos is literally just an evil version of him/them, do you suppose he hails from the Mirror Multiverse? If he's a copy of an evil Irvine Kinneas, aka an FFVIII where Squall's group are the antagonists, that seems to match what we know of Master Who, where the Daleks were protagonists.

"It's That Talk Again" - To my mind, this calls up chronic FicPsych patients (Jeanine Guiles, Chelsea Miller, etc.) The early lines are the psychiatrist trying to nurse the agent's mental health back, with the agent resisting:

I never meant for this to last
We turn around, a year has passed
And now you've got these thoughts in your head
You never heard a word I said
It's that talk again

The chorus is the patient fighting treatment, afraid to face whatever sent them there:

When all I have to say
Would fill your heart with pain
So let's just walk away

The last verse is the former partner visiting with their friends/current partner, being supportive of the patient's recovery.

I see you in the crowd with your friends again
...
It never really ends
I might have a girl on my arm again
Then you'll want to weave and pretend we never met
But don't do it, don't do it
It's that talk again


"Two Against One" - A lot of the lines here remind me of the "clashing mindsets" dynamic the Flowers like to use in partnering people.

I keep my enemies closer than my mirror ever gets to me
And if you think that there is shelter in this attitude
Wait til you feel the warmth of my gratitude

—doctorlit means to sign his posts from now on, but keeps forgetting.

"Shakin' All Over" makes me think of brainwashed canons being forced into a 'ship from an author wraith's influence.

When you move in right up close to me
That's when I get the shakes all over me

...

Just the way that you say goodnight to me
Brings that feelin' on inside of me

"See, the Conqu'ring Hero Comes" - For some reason, my brain is adamant that this played ironically over the Master Who Daleks rescuing HQ from the Macroviruses.

"Idiot Control Now" - This makes me think of the line-up of vehicles DoSAT keeps. (We've seen the spaceships; I figure they must have road-based stuff, too.) The things those vehicles must see/be used for when agents are using them on missions . . . Not to mention how some agents must treat them!

Steady as a goat
We're flying over trout
Ghetto down the highway
At the speed of light

I can just imagine this one playing when a Suethor or a recruited Sue finally realize how much harm they have done to canon and they want to atone for this.

All of those optical illusions make it look like something out of HQ's Escher Room!

As for me, this is what I've got:

Fortunate Son by Creedence Clearwater Revival

The Magnificent Seven by the Clash

Peril by Martin O'Donnell and Michael Salvatori

I can just imagine this playing when an angent snaps,takes a flamethrower and goes "argue" with the Flowers about the Duty.

And now for the next salvo :

-Maze of Life by Yumi Kawamura, Shihoko Hirata for the song and Shoji Meguro for the composition.

-Unbreakable Tie by Lotus Juice and Asami Izawa

-I Need a Villain by O.D.I.L. and the Flander's Company.

...even though it means admitting I ship Kayleigh/Salamander. (Poor Sal.)

The song definitely has the sort of cheerfulness I associate with Kayleigh with some of the random.

Geek in the Pink. Jason Mraz.

Knuckle Down by Man Man.

I think it's the video that sells it - all that stilted, unnatural formalism.
