• Para (TO): Es el más utilizado y el más conocido por todos. Aquí incluímos las direcciones de los destinatarios, siempre que no nos importe que cada uno de ellos pueda ver a quién se le ha enviado el correo.
• CC: Es la abreviación de Carbon Copy. Es exactamente igual al campo Para, pero con la diferencia de que las direcciones puestas en CC recibirán una copia del correo y todos los que lo reciban sabrán que se ha enviado dicha copia y a quién se le ha enviado.
• CCO (BCC): Es la abreviación de Blind Carbon Copy. Los que aparezcan en este campo recibirán una copia oculta.

En resumen, los tres campos sirven para lo mismo y la decisión de en cuál de ellos se pone una dirección vendrá dada por si el mensaje va o no directamente dirigido a esa persona y si se quiere o no ocultar la dirección del resto de receptores del mensaje.

Letra:

¿Qué din os rumorosos
na costa verdecente
ao raio transparente
do prácido luar?
¿Qué din as altas copas
de escuro arume arpado
co seu ben compasado
monótono fungar?

Do teu verdor cinguido
e de benignos astros
confín dos verdes castros
e valeroso chan,
non des a esquecemento
da inxuria o rudo encono;
desperta do teu sono
fogar de Breogán.

Os bos e xenerosos
a nosa voz entenden
e con arroubo atenden
o noso ronco son,
mais sóo os iñorantes
e féridos e duros,
imbéciles e escuros
non nos entenden, non.

Os tempos son chegados
dos bardos das edades
que as vosas vaguedades
cumprido fin terán;
pois, donde quer, xigante
a nosa voz pregoa
a redenzón da boa
nazón de Breogán.

Teus fillos vagorosos
en que honor soo late,
a intrépido combate
dispondo o peito van;
se, por ti mesma, libre
de indigna servidume
e de oprobioso alcume,
rexión de Breogán

Á nobre Lusitania
os brazos tende amigos,
ós eidos ben antigos
con un punxente afán;
e cumpre as vaguedades
dos teus soantes pinos
duns máxicos destinos,
¡oh, grei de Breogán!

Amor da terra verde,
da verde terra nosa,
acende a raza briosa
de Ousinde e de Froxán;
que aló nos seus garridos
xustillos, mal constreitos,
os doces e albos peitos
das fillas de Breogán;

que á nobre prole insinen
fortísimos acentos,
non mólidos concentos
que ás virxes só ben están;
mais os robustos ecos
que, ¡oh, patria!, ben recordas
das sonorosas cordas
das arpas de Breogán.

Estima non se alcanza
cun vil xemido brando;
calquer requer rogando
con voz que esquecerán;
mais cun rumor xigante,
subrime e parecido
ao intrépido sonido
das armas de Breogán.

Galegos, sede fortes,
prontos a grandes feitos;
aparellade os peitos
a glorioso afán;
fillos dos nobres celtas,
fortes e peregrinos,
luitade plos destinos
dos eidos de Breogán.

Letra:

Going back to the corner where I first saw you,
Gonna camp in my sleeping bag I’m not gonna move,
Got some words on cardboard got your picture in my hand,
Saying if you see this girl can you tell her where I am,
Some try to hand me money they don’t understand,
I’m not…broke I’m just a broken hearted man,
I know it makes no sense, but what else can I do,
How can I move on when I’m still in love with you…

Cos if one day you wake up and find that you’re missing me,
And your heart starts to wonder where on this earth I can be,
Thinking maybe you’ll come back here to the place that we’d meet,
And you’d see me waiting for you on the corner of the street.

So I’m not moving…
I’m not moving.

Policeman says son you can’t stay here,
I said there’s someone I’m waiting for if it’s a day, a month, a year,
Gotta stand my ground even if it rains or snows,
If she changes her mind this is the first place she will go.

Cos if one day you wake up and find that you’re missing me,
And your heart starts to wonder where on this earth I can be,
Thinking maybe you’ll come back here to the place that we’d meet,
And you’d see me waiting for you on the corner of the street.

So I’m not moving…
I’m not moving.

I’m not moving…
I’m not moving.

People talk about the guy
Who’s waiting on a girl…
Oohoohwoo
There are no holes in his shoes
But a big hole in his world…
Hmmmm

and maybe I’ll get famous as man who can’t be moved,
And maybe you won’t mean to but you’ll see me on the news,
And you’ll come running to the corner…
Cos you’ll know it’s just for you

I’m the man who can’t be moved
I’m the man who can’t be moved…

Cos if one day you wake up and find that you’re missing me,
And your heart starts to wonder where on this earth I can be,
Thinking maybe you’ll come back here to the place that we’d meet,
And you’d see me waiting for you on the corner of the street.

So I’m not moving…
I’m not moving.

I’m not moving…
I’m not moving.

Going back to the corner where I first saw you,
Gonna camp in my sleeping bag not I’m not gonna move.

Letra:

Oh brother I can’t, I can’t get through
I’ve been trying hard to reach you, ’cause I don’t know what to do
Oh brother I can’t believe it’s true
I’m so scared about the future and I wanna talk to you
Oh I wanna talk to you

You can take a picture of something you see
In the future where will I be?
You could climb a ladder up to the sun
Or write a song nobody has sung
Or do something that’s never been done

Are you lost or incomplete?
Do you feel like a puzzle, you can’t find your missing piece?
Tell me how (do) you feel?
Well I feel like they’re talking in a language I don’t speak
And they’re talking it to me

So you take a picture of something you see
In the future where will I be?
You could climb a ladder up to the sun
Or write a song nobody has sung
Or do something that’s never been done
Do something that’s never been done

So you don’t know were you’re going, and you wanna talk
And you feel like you’re going where you’ve been before
You tell anyone who’ll listen but you feel ignored
Nothing’s really making any sense at all
Let’s talk, let’s ta-a-alk
Let’s talk, let’s ta-a-alk

Letra:

Lights go out and I can’t be saved
Tides that I tried to swim against
Have brought me down upon my knees
Oh I beg, I beg and plead; Singing

Come out of things unsaid
Shoot an apple off my head
And a trouble that can’t be named
A tiger’s waiting to be tamed; Singing

You are
You are

Confusion that never stops
Closing walls and ticking clocks
Gonna come back and take you home
I could not stop, that you now know; Singing

Come out upon my seas
Cursed missed opportunities
Am I a part of the cure?
Or am I a part of the disease?; Singing

You are, you are
You are, you are
You are, you are
You are, you are

And nothing else compares
And nothing else compares
And nothing else compares
And nothing else compares

You are,you are

Home, home, where I wanted to go
Home, home, where I wanted to go
Home, home, where I wanted to go (you are)
Home, home, where I wanted to go (you are)

Letra:

I used to rule the world
Seas would rise when I gave the word
Now in the morning I sleep alone
Sweep the streets I used to own

I used to roll the dice
Feel the fear in my enemy’s eyes
Listen as the crowd would sing:
“Now the old king is dead! Long live the king!”

One minute I held the key
Next the walls were closed on me
And I discovered that my castles stand
Upon pillars of salt and pillars of sand

I hear Jerusalem bells are ringing
Roman Cavalry choirs are singing
Be my mirror my sword and shield
My missionaries in a foreign field

For some reason I can’t explain
Once you’ve gone there was never,
Never an honest word
And that was when I ruled the world

It was the wicked and wild wind
Blew down the doors to let me in
Shattered windows and the sound of drums
People couldn’t believe what I’d become

Revolutionaries wait
For my head on a silver plate
Just a puppet on a lonely string
Oh who would ever want to be king?

I hear Jerusalem bells are ringing
Roman Cavalry choirs are singing
Be my mirror my sword and shield
My missionaries in a foreign field

For some reason I can’t explain
I know Saint Peter won’t call my name
Never an honest word
But that was when I ruled the world

Oooohhh Oooohhh

I hear Jerusalem bells are ringing
Roman Cavalry choirs are singing
Be my mirror my sword and shield
My missionaries in a foreign field

For some reason I can’t explain
I know Saint Peter won’t call my name
Never an honest word
But that was when I ruled the world
