[Letra]:One
Disco: Achtung Baby

Is It getting better, or do you feel the same?
Will it make it easy on you now, you've got someone to blame?

You say, one love, one life, i'ts one need,In the night,
One Love, get to share it, leaves your darling, If you don't care for it

Did I Disappoint You?
Or leavea a bad taste in your mouth?
You act like you've never had love
And you want me and go without

Well i'ts too late, tonight.
To drag the past out into the light,
We're one, but we're not the same
We get to carry each other, carry each other, one...

Have you come here for forgiveness?
Have you come to raise the dead?
Have you come here to pray Jesus,
to the Lappers in your head?
Work it out, as a strong voice running a lot,
you gave me nothing now it's all i've got
We're one, but we're not the same,
If we hurt each other then we'll do it again

You Say, Love Is A Temple, Love Higher A Law,
Love Is A Temple,Love a Higher Law
You ask to me to enter, but then you make me crawl,
And I Can't Be Holding On
To What You Got it, When All You Got Is Hurt

One Love, One Blood ,One Life
You Got To Do What You Should

One Life, With Each Other : sisters and my brothers

One Life
But We're Not The Same
We Get To Carry Each Other
Carry Each Other

One

One love, one
