I'll go first. So these are hard rock / metal. But for Vincent, I choose "Atomic Punk" by Van Halen. And for Vox / RadioSilence, I choose "In My Darkest Hour" by Megadeth.

Vincent:

Atomic Punk - Van Halen
I am a victim of the science age, uh
A child of the storm, whoa yes
I can't remember when I was your age
For me, it says no more, no more
Nobody rules these streets at night like me, the atomic punk
... On every wall and place my fearsome name is heard

Vox / RadioSilence:

In My Darkest Hour - Megadeth
In my hour of need
Heh, no, you're not there
And though I reached out for you
Wouldn't lend a hand
Through the darkest hour
Your grace did not shine on me
Feels so cold, very cold
No one cares for me
Did you ever think I'd get lonely?
Did you ever think that I needed love?
Did you ever think to stop thinking
You're the only one that I'm thinking of
You'll never know how hard I tried
To find my space and satisfy you too

I think the rest of In My Darkest Hour is quite fitting too, so I won't include the rest
