Si una vez [English translation]

I gave you all my love and more

and you can't even recognize love

I put myself at your feet

and you pay me with contempt

but now look

if I once told you that I loved you

today I regret it

if I once told you that I loved you

I don't know what I was thinking, I was crazy

if I once told you that I loved you

and I would give my life up for you

if I once told you that I loved you

I won't do it again

that's an error of the past

I know one day you'll come back

and you'll be sorry for everything

I put at your disposal and look at how you pay me

but now look

if I once told you that I loved you

today I regret it

if I once told you that I loved you

I don't know what I was thinking, I was crazy

if I once told you that I loved you

and I would give my life up for you

if I once told you that I loved you

I won't do it again

that's an error of the past
