No, Really - Go lyrics

Let me make this clear It doesn't matter why I came here For the city, for the music, or for you The only thing that matters is that When you are not here The city's empty and the music's out of tune I hope you still feel The same when you get back I hope I still remember how you felt before you left Could you come back as someone else And would I ever know? Or am I the one who changes when you go? When you go When you go Or am I the one who changes when you go? I've been traveling myself Alone with no one else Half a world away from where I call my home But nothing looks the same Without you there to see it with me I need your eyes in addition to my own When you go When you go Or am I the one who changes when you go?
