Translation of the song lyrics Hoy - Armando Manzanero

Hoy (original)

Hoy, me prometí que te tengo que olvidar
Aunque en las noches me enferme de pesar
Y que no vuelva jamás a suspirar
Hoy, aunque hayas sido mi único querer
Me prometí que me tengo que imponer
El sacrificio de no volverte a ver
Hoy, el sol me dijo que tú amor era mi error
Que no me has dado ni cariño ni calor
Que sólo hicistes más grande mi dolor
Hoy, por ser tan tuya no me vuelvo a preocupar
Ni con tus besos me vuelvo a equivocar
Por Dios te juro que te tengo que olvidar
Hoy, hoy

Hoy (translation)

Today, I promised myself that I have to forget you
Although at night I get sick of regret
And may he never sigh again
Today, although you have been my only love
I promised myself that I have to impose myself
The sacrifice of not seeing you again
Today, the sun told me that your love was my mistake
That you have not given me love or warmth
That you only made my pain bigger
Today, because I'm so yours, I don't worry again
Not even with your kisses will I make a mistake
For God I swear that I have to forget you
Today today
