Honestly, Gale and Astarion's Romance routes feel very Hozier-coded?
For Gale specifically, I'd put Sedated, Cherry Wine, Almost (Sweet Music), Wasteland, Baby!, Francesca, and Who We Are. There's that implicit understanding that Mystra broke him on some fundamental level that he feels like he'll never recover from and, even with that pain, he's still chasing her forgiveness and acceptance because that's where he found worth as a person. However, on top of the literal bomb in his chest, he finds himself with an illithid tadpole in his brain, completely abandoned by his goddess under a SECOND, much faster death sentence. Then he meets the player character who gives him a reason to try to live and love again (even in this horrible, fucked up situation) and find worth in himself beyond Mystra and her gifts. Initially, he feels like he has to treat the player like he would his past lover, specifically when it comes to their physical relationship, but the player can help him past that easily. The echo of that relationship is going to haunt him, probably for the rest of his life, but it isn't the only thing in his life, and he's choosing to love the player even in this hellish apocalypse he's found himself in.
Just a little rush, babe, to feel dizzy
To derail the mind of me
Just a little hush, babe; my veins are busy
But my heart's in atrophy
Her fight and fury is fiery
Oh but she loves
Like sleep to the freezing
Sweet and right and merciful
I'm all but washed
In the tide of her breathing
And it's worth it, it's divine
I have this some of the time
You and I burned out our steam
Chasing someone else's dream
How can somethin' be so much heavier
But so much less than what it seems?
Darling, we sacrificed
We gave our time to somethin' undefined
This phantom life sharpens like an image
But it sharpens like a knife
I'll tell them put me back in it
Darling, I would do it again, ah, ah
If I could hold you for a minute
Darling, I'd go through it again, ah, ah
I would still be surprised I could find you, darling
In any life
If I could hold you for a minute
Darling, I would do it again, ah, ah
The same kind of music haunts her bedroom
I'm almost me again, she's almost you
And I love too
That love soon might end
And be known in it's aching
But shown in the shaking
Lately of my wasteland, baby
Be still, my indelible friend
You are unbreaking
Though quaking
Though crazy
That's wasteland, baby
Astarion gets Take Me To Church, Jackie and Wilson, Someone New, Work Song, Nobody, Talk, First Time, All Things End, and First Light. He spends two hundred years feeling like an inhuman monster, twisted into a tool for Cazador only worth his body and honeyed words. Unlike Gale, Astarion sees the tadpole as a gift, saving him from the life of a slave that he never wants to return to. When he meets the player, he recognizes weakness and repeats that same pattern of securing safety with what Cazador taught him. In the end, the right path for the player to take with him is to teach him that he can be accepted and loved as the mess he sees himself as with worth beyond what Cazador broke him down to, and it's an incredible experience for him. They are the first person he truly cared for besides himself and he'd do anything to stay with them.
Every Sunday's getting more bleak
A fresh poison each week
"We were born sick", you heard them say it
My church offers no absolutes
She tells me, "Worship in the bedroom"
Onе bright mornin' goes so easy
Darkness always finds you either way
It creeps into the corners as the moment fades
A voice your body jumps to callin' out your name
But after this, I'm never gonna be the same
And I am never going back again
Don't take this the wrong way
You knew who I was with every step that I ran to you
Only blue or black days
Electing strange perfections in any stranger I choose
I won't deny I've got in my mind now (Hey, yeah)
All the things I would do
So I try to talk refined for fear that you find out (Hey, yeah)
How I'm imaginin' you
A two-tonne weight around my chest feels like
It just dropped a twenty-storey height
If there was anyone to ever get through this life
With their heart still intact, they didn't do it right
Remember once I told you about
How before I heard it from your mouth
My name would always hit my ears as such an awful sound?
And the soul, if that's what you'd call it
Uneasy ally of the body, it felt nameless as a river
Undiscovered underground
She blows outta nowhere, roman candle of the wild
Laughing away through my feeble disguise
No other version of me I would rather be tonight.
And, Lord, she found me just in time
Boys, when my baby found me
I was three days on a drunken sin
I woke with her walls around me
Nothin' in her room but an empty crib
And I was burnin' up a fever
I didn't care much how long I lived
But I swear I thought I dreamed her
She never asked me once about the wrong I did
When my time comes around
Lay me gently in the cold dark earth
No grave can hold my body down
I'll crawl home to her
I'd be appalled if I saw you ever try to be a saint
I wouldn't fall for someone I thought couldn't misbehave
But I want you to know that I've had no love like your love
