Person 2: Zon Kuthon, it's about delighting in evil, the ending is the real clincher, "it get so lonely being evil" because of what he used to be, and how Dou-Bral may be somewhere down in there.
It's not perfect, but I was thinking Naderi, goddess of suicide, particularly romantic suicide, which is certainly one hell of a way to say "count me out!"
"I will stay in the mess I've made", appeals to loyalty, promises of deliverance, violence, a sort of militaristic feel but too much talk of otherworldly concerns to be Gorum... I would say Asmodeus.
Cayden Cailean, definitely. At its heart, the song is telling you to reject all traditional wisdom and just jump in and do what's right. Does it seem stupid? Yes, but often bravery seems stupid to the frightened.
That one's pretty easy: Pharasma - it's even called "Lament."
I would associate Gollum's Song with Gyronna, minor goddess of spite and hatred. I actually don't think self-pity is Urgathoa's thing.
Tangential, then, to both Lord of the Rings soundtrack singers (that one) and songs that force you to make a saving throw or be stunned by an overwhelming aura of The 80's ("This Corrosion") is Sweet Dreams
For some reason, that makes me think of Aroden... But I'm not skilled enough at youtubery to post a song, can't think of one. So I'll just post my opinion and move on.
Now, I can never tell the subject matter of a song unless it says so blatently. The lyrics match Gozreh, but I can't tell you what the subject's diety is.
Imbrex, the First World deity of endings, statues, and twins. Put them all together and it almost makes sense - bear in mind the double meaning in "getting/being stoned."
The Diabolism faith (which worships the plane of Hell itself and its structure rather than Asmodeus or any of the archdevils), naturally - don't let anyone confuse you: Mob rule is a beast of law and order in its purest state.
The serious, though, is a little more complicated. It might be Gorrum. Strong beats are common in Techno songs, and are also common place in battlefields and drink halls. Bagpipes are also one of the most iconic musical instruments of Scottland, who are notoriously known for their big swords and love of fighting.
But on the same note, the driving motion of the song will keep you in step and will make sure you keep moving. As such, Desna, the goddess of Traveling, works as well. The sweet tone of the song also implies a womens touch, but this is subjective.
Oddly enough, Caddyn Caelyn would work as well, since the song is easy going and could easily be heard in a tavern. Imagine 10-20 people clapping to this song while drinking and cheering to understand what I'm talking about.
I for my Silly/Serious ones, here is
Safety Dance by Men Without Hats
Behold a Pale Horse by Martin O'Donnel and Michael Salvatori
Safety Dance - "We can act like we come from out of this world, leave the real world far behind?" I think I'll give this one to The Lantern King, trickster god of the Eldest.
Behold a Pale Horse - Besmara? There's at least a part where it gets pretty pirate-shippy.
Somebody that I used to Know- Shoot me if you will, but I'd call it Erastil's. His way of life is being shoved out of the way, and his churches abandoned as things developed. He also seems to be the most turned-away from deity in the campaigns I've seen.
Garden of your Mind-
Chaldira Zuzaristan. Despite being a halfling goddess instead of a gnomish one, she's impetuously curious, and never afraid to ask for help. Or we could say Norgerber if we felt silly.
Through Heaven's Eyes - a song about the value of an individual being powerful if not obvious, strong "populist" appeal - so a good candidate for Cayden Cailean, actually.
Urban Spaceman - nihilism, nonexistence, supersonic flight...why not Groetus?
Theatre of Magic-Nethys; I imagine magic of all sorts when I hear this, and the dual string types make me think of a schizo'd mind(though they're nicely balanced, another part of the anathema of Nethys). Also, it's in the name. XD
What would Brian Boitano Do- Cayden Caylean, again, on account of the escalating madness; I'd buy Iomedae, too, if I'd ever seen a cleric or paladin in hers without a stick up their ass (I assume its a fixture of the faith).
