DESCRIPTION:
I love this song and this episode so much that I decided to practice my Spanish by translating the lyrics. I've changed the phrasing of some lines slightly in order to keep the rhyme scheme but the meaning is basically the same. I'm not a native Spanish speaker, so if you notice any mistakes or have advice on ways I could improve the translation then please let me know in the comments :)

Song: Walk Through the Fire/Andar por el fuego
TV show: Buffy the Vampire Slayer
Episode: Once More, With Feeling

English lyrics:

[Buffy:]
I touch the fire and it freezes me
I look into it and it's black
Why can't I feel?
My skin should crack and peel
I want the fire back

Now through the smoke she calls to me
To make my way across the flame
To save the day or maybe melt away
I guess it's all the same

So I will walk through the fire
Cause where else can I turn?
I will walk through the fire
And let it

[Spike:]
The torch I bear is scorching me
Buffy's laughing I've no doubt
I hope she fries
I'm free if that bitch dies
I'd better help her out

[Sweet:]
Cause she is drawn to the fire
Some people never learn
[Spike:]
She will never learn
[Spike and Sweet:]
And she will walk through the fire
And let it

[Giles:]
Will this do a thing to change her?
Am I leaving Dawn in danger?
Is my slayer too far gone to care?

[Xander:]
What if Buffy can't defeat it?
[Anya:]
Beady Eyes is right, we're needed
Or we could just sit around and glare

[Group:]
We'll see it through
It's what we're always here to do
So, we will walk through the fire

[Buffy:]
So one by one they turn from me
I guess my friends can't face the cold
[Tara:]
What can't we face if we're together?
[Buffy:]
But why I froze
Not one among them knows
And never can be told

[Sweet:]
So one by one they come to me
The distant redness as their guide
But what they'll find
Ain't what they have in mind
It's what they have inside

[Anya:]
She came from the grave much graver
[Spike:]
First he'll kill her then I'll save her
[Tara:]
Everything is turning out so dark
[Spike:]
No, I'll save her then I'll kill her
[Willow:]
I think this line's mostly filler
[Giles:]
What's it gonna take to strike a spark?

[Buffy:]:
Going through the motions
Walking through the part
These endless days
Are finally ending in a blaze

[Sweet:]
She will come to me

[Buffy, Spike and Group:]
And we are caught in the fire
The point of no return
So we will walk through the fire
And let it burn
Let it burn
Let it burn
Let it burn!

(My) Spanish translation (traducción al Español):

[Buffy:]
Toco el fuego y me congela
Miro en lo y es negro
¿Por qué no puedo palpar?
Mi piel debe agrietar y pelar
Quiero el fuego de nuevo

Ella me llama a través del humo
Para ir más allá de las llamas
Yo salvaré el día o me convertiré en cenizas
Supongo que no importa

Así que yo andaré por el fuego
Porque no tengo una opción
Yo andaré por el fuego
Y lo dejaré

[Spike:]
La antorcha que aguanto es ardiendo me
Buffy se ríe, no tengo duda
Espero ella arde
Estoy libre si la bruja muere
Debo dar a ella ayuda

[Sweet:]
Porque ella tiene atracción al fuego
[Sweet/Spike:]
Alguna gente nunca aprenderá/Ella nunca aprenderá
[Sweet & Spike:]
Y ella andará por el fuego
Y lo dejará

[Giles:]
¿Aún este cambiará cualquier cosa?
¿Estoy poniendo Dawn en problemas?
¿Buffy está más allá de sentir algo?
[Xander:]
¿Y si Buffy no puede lo derrotar?
[Anya:]
Ojos Pequeños es correcto, nos necesita
O podríamos sentarse y estar mohíno

[Todos:]
Lo veremos a través
Es qué siempre hacemos
Así que andaremos por el fuego

[Buffy:]
Uno por uno, se apartan de mí
Supongo que mis amigos temen al frío
[Tara/Buffy:]
¿Qué debemos temer/Pero nadie sabe
[Tara/Buffy:]
si estamos juntos?/la razón soy insensible
[Buffy:]
y nunca será conocido

[Anya/Sweet:]
Ella vino de la tumba grave/Uno por uno
[Spike/Sweet:]
Él mata ella, luego la salvaré/vienen a mí
[Tara/Sweet:]
Todo ha salido tan oscura/El rojo lejano es sus guía
[Buffy:]
Viviendo maquinalmente
[Spike/Sweet:]
No, yo salvaré ella, luego la mataré/Pero qué encuentran
[Willow/Sweet:]
Creo que esta línea no es necesaria/no es qué esperan
[Giles/Sweet:]
¿Qué debo hacer para crear una chispa?/Es qué hace sus esencia
[Buffy/Sweet:]
Estos días sin fin son finalmente ardiente/Ella vendrá a mí

[Todos:]
Y estamos atrapados en el fuego
El punto donde no podemos volver
Así que andaremos por el fuego
Y lo dejaremos
Arder
Lo dejaremos arder
Lo dejaremos arder
¡Lo dejaremos arder!
