I´ve tried to translate this song. If anyone sees any correction, please post...

Söz - Müzik: Burcu Güneş

Uzağına Düştüm – I’ve Fallen Apart From You

Bu son çağrım, duyacağın en son ses – This is my last call, the last you’ll hear of my voice

Benden sana son ışık, parçalanmadan gel – My last gleam to you, take it apart

Günah bende, nasıl sevdim seni böyle? – The sin is mine, how could I have loved you like this?

Anlamak mümkün değil, yok oldun şaka gibi - Impossible to understand, you haven’t become a joke

Kaçsanda ben burdayım, başım dik ayaktayım - ???

Bu sonu sen hazırladın – This ending you arranged

Gözüm arkada kalmadı, hiç bu defa – My eyes stayed behind, not this time

Uzağına düştüm, ben sana küstüm – I’ve fallen apart from you, I’m upset with you

Gidiyorum gözünaydın – Congratulations, I’m leaving

İçime ata ata nasıl üzgün - ???

Thanks so much. 2 things I´m still stuck on.

How does şaka gibi become this has to be a joke?

Bu sonu sen hazırladın – You had it coming

Is this an expression? I thought hazırlamak was to prepare or arrange, meaning the guy wanted this to happen.

Well, I´ve added my interpretation to it, of course.

şaka gibi literally means it´s like a joke, and it´s the equivalent of the expressions, "you gotta be kidding me", "this is unreal" or "this has to be a joke", in English. I´m not sure if "it´s like a joke" is a common expression in English, could be.

Bu sonu sen hazırladın=You prepared this ending. Yes, this is an expression. It means you are responsible for this (bad consequence). Relate it to the song, it says "I´m leaving, congrats." in other words, "you deserved this", "you had this coming". Another expression like this is "kendi sonunu hazırlamak" which means to do something(bad) to yourself, or to dig yourself into a hole.
